Wally, if you separate the arm actions into those prior to the lowest point of the chord and those after the chord, you might be able to make more sense of ROWING vs. PULLING.
Prior to the chord, your phrase above is accurate, except it's not called ROWING. Rowing is during the inversion, but not during the takeoff or swing.
The action of moving from the "C" position to the "I" position - where your entire body is straight, just before the chord - is simply part of the SWING. On a highbar, this same action is moving from the C to the I - where your body is almost directly under the bar.
You're right - this is all GOOD! But it's not ROWING. It's simply part of the swing, wherein your top arm and your trail leg swing in unison from the C to the I. Using my BB technique, I initiated this swing by the trail leg action, whereas Agapit proposes (in the 6.40 model) to initiate this action by the top (and bottom) arms. If you ignore the bottom arm for a moment (a 6.40 model technique only, I believe), then the differences between my approach and Agapit's are very, very minor. In fact, they both coincide quite closely to what Altius recommends in BTB2 (i.e. the "pure" Petrov model).
This is the wrong thread to discuss the differences between BB and 6.40, so I won't go there now. I just want to make sure you understand the similarities and distinctions that you'll hear from various sources.

Very briefly, according to the Petrov model ...
On/after takeoff, you should STRETCH your top arm as much as possible, in unison with STRETCHING the trail leg as much as possible, by following thru on takeoff (i.e. finishing the takeoff). Included in this STRETCHING action is letting your chest drive forwards (i.e. not resist a full stretch of the top arm above and behind the head). This should put you into a good C position, which you SHOULD NOT pause in. YES, you want to PASS THRU the C position, but NO, you should not PAUSE in that position, as that would be a passive action (i.e. lack of action - lack of continuous body motion).
If Altius wants to clarify anything here, that's fine - let's go with his explanations, as per BTB2. This is just off the top of my head, from my own personal experience.
As you go from the C to the I, you swing your trail leg and "lat pull" your top arm as long and as quickly as you can. This is where you "make or break" your vault. If you're fast, you'll have the momentum to swing with a natural, continuous motion into an inverted position. If you're too slow, you won't become fully inverted, so you'll have to ROW to finish your inversion. In that case (which is the most likely the case with most non-elite vaulters), the rowing action with BOTH arms is recommended.
Many vaulters combine this rowing action with a tuck, but it's definitely much better to row than to row AND tuck. And I would guess that almost every tuck/shoot vaulter not only tucks, but also ROWS to get into the tuck. This is possibly where misconceptions are formed, as it's not the ROWING part of the tuck/shoot technique that's bad (as much), it's the TUCKING.
Maybe think of it in 3 categories ...
1. Those that don't row or tuck - the true Petrov model vaulters
2. Those that row but don't tuck - the Petrovers that are trying to salvage a vault after a poor swing
3. Those that row and tuck - the tuck/shooters.
I hope this clarifies what you should do (and not do) with your arms while you takeoff, swing, and invert - with respect to ROWING.
I admit that the above is a very brief explanation, leaving out a lot of details. Perhaps instead of arguing about the details, we can just agree on the high-level principles?
I do expect some argument from some posters that will quote Agapit's 6.40 model. Remember that you need to separate the technique that a potential WR-setter might use, vs. the technique that a non-elite vaulter might use. You aren't yet an elite vaulter, Wally, so I recommend that you NOT attempt to follow the 6.40 model. Just follow the Petrov model, and worry about the 6.40 model once you get over 19'+. In fact, to my knowledge, there's even very few 19'+ vaulters that follow the 6.40 model ... so far!
