in/out of bounds

[dguig]

I've got two scenarios.. please let me know if I'm correct on the 1st and what is the call on the 2nd..

1st.. A1's team has ball.. B1 is screened on the end line. To avoid the screen, B1 steps out of bounds then re-enters the court. Is a technical called on B?

2nd.. A1 has ball and B1 is defending. While driving upcourt, along the sideline, A1 and B1 have incidental contact, the ball is momentarily loose (in-bounds), A1 steps out of bounds, re-enters and re-gains possession of the ball..

What is this call?

I was at one game as a coach where a ref said this was legal but I disagreed.
