On one hand, I don't have the slightest idea of how an IO officer's mind (?) works. On the other, I don't think a copy would be accepted, since the sheet has an impressed sign to indicate that it's real. I don't know if you've seen one of these Squirrel, but it's hard to believe that it's an official document. It's just two single-sided A4 pages that are stapled together, an ink stamp, and a signed seal. It looks so ordinary, off-handedly produced, and easy to forge that it would be, imo, very easy to misplace or lose.
