I will also stick up a bit for the PU here, speaking as if I was the PU. It is entirely possible that when this ball was hit, the PU saw that it might be a trouble ball, and focused on the fielders and the catch/no catch. He may not have picked up the the BU chased. If I was PU in a two umpire system on this play, I would not expect my partner to chase with 2 or 3 runners on base. That being said, I would still be out in the infield toward where the play was made and not standing behind the plate.

More good possibilities. Even more reason to not decide, as BU, to never go out again with this partner, and instead to go discuss with partner in between innings.
