yes, it is, no matter how brief. You'll want to make sure there's a way to prove it remains completely legal the entire time it's extending/standing up (not just math, but Physical proof), and make sure it's both clear and repeatable that it's legal. The inspectors will want to take a close look at it, and they'll tell the refs "it's ok so long as it moves like this...". That conversation will most likely happen while you're on the field so the head ref can be watching you extend while the LRI is telling him it's legal.
