7.1.1 SITUATION A: A1, while holding the ball inbounds near the sideline,
touches (a) player B1; (b) a photographer; (c) a coach; (d) an official, all of whom
are out of bounds. RULING: A1 is not out of bounds in (a), (b), (c) or (d). To be
out of bounds, A1 must touch the floor or some object on or outside a boundary
line. People are not considered to be objects and play continues. Inadvertently
touching someone who is out of bounds, without gaining an advantage, is not
considered a violation.

Key phrase here. If they are doing it to gain an advantage, then it is a violation. If the offense is falling out of bounds and puts their hands on the official to keep their balance and they stay inbounds.
