Thirdly, even if U2 was outside, he's still probably going to miss the OBS. His eyes, as you mentioned, are on the ball AND the play occurs after 2B. U3 has the best view, as he's at 3B watching the ball being fielded, which puts OBS in direct line of his watching the play.

About 25 seconds into this video:

In the same video you see an umpire taking this play from behind, from deep C, and standing right in the cutout.
