this is exactly what I was thinking today on the swimingpool... was hasitaiting which techniques to chose. I have seen both fro mthe professional swimers and got a little bit confused.
Illustrating a movement idea while standing up and wearing a jacket? The viewer will have to interpret what those movements translate to in the water, which can be done in a number of ways.
really like your viewpoint on this, but its a shame the swimmer in the green cap wasn't demonstrating catch up as her propulsion arm moved before catch up and head returning to water, plus she crossed and entered thumb first, the two latter much easier to put right before the tricky timing thing, but keep it up
