One will take precedence over the other during a live ball in bounds. BC takes precedence over FC if a player is touching both. OOB takes precedence over IB if the player is touching both. During a throw in, it's slightly different. The player is only allowed to be OOB. Once he gets OOB, he must stay there until the ball is released on a pass. You call the violation for the same reason you call a violation if he hands it off to a teammate or if he lets even one toe touch the court in bounds before he releases the pass.

In your new situation, she is attempting to pull the ball OOB to secure it for a throwin. No violation. In the original situation, she is attempting to short cut the rule by batting the ball. If the ball is in the air (bouncing) when she bats it, legal. If it's on the floor, the ball is now both in bounds and out of bounds; this is the violation.
