Well, if you believe implementation, my NeXT computer (Display PostScript
version 2000.6) yields the following answers:

  1) yes, restore undoes the effects of bind
  2) no, it doesn't seem to work with packed arrays

I presume that you already did some testing before you posted your
question, and that what you are really asking for is clarification
from Adobe, but I thought that some implementation results might help
shed some light on the issue.
