Maybe it's a case of one gear (nose in this case) retracting before the others? I've
noticed many airplanes where each gear retracts at different rates, or one part of the
gear retracts before the others. I think it just has to do with how the hydraulics are
run and all that. Not sure about this case though.
Gears :
You are right.
It is a sequence, to lighten the burden of the pump :
1. Nose gear (283 lb),
2. (Right) main gear (747 lb),
3. (Left) main gear (747 lb).

You clearly see it on videos.



Floats :
Both floats are actuated together by a single power gear box.
