Wht do you mean, you wonder why he didn't email you? He very obviously has a DESPERATE need to make this as difficult as possible for you and never to make so much as a keystroke on a computer on your behalf if he can help it. My guess from your description is it would have looked bad to the wrong other people for him to delay signing it any more, and that's why he bothered, but he wants you to twist in the wind absolutely as much as possible.

GLAD you got the signed paper

HOPE the resubmission flies !!!!

Have a good bike ride to channel the stress...
