Agree w/ PitchingFan on both. If you were the defensive coach - would you want the call? Read up on 7-3-5 for the first and 8-3-3(d) for the second. If you have a casebook 7.3.5 situation E.
No such thing as the catcher should create the throwing lane. Think runners lane interference to first... Steal of second and batter loses balance and crosses plate. The throw to 3rd is tough because you are right the batter cannot disappear, but you have to judge movement and cannot assume intent. It ends up being control - he knew the H&R was on and he's doing anything to hit that ball (like a suicide squeeze).
The casebook does say a batter "is entitled to his position in the batter's box and is not subject to being penalized for interference unless he moves or re-establishes his position after F2 has received the pitch, which then prevents F2 from attempting to play on a runner. Failing to move so F2 can make a throw is not batter interference."
