I could be wrong, but my guess as to why he does it that way is that a number of email system don't let zip files or executables through. This way, he hides the executable in the first zip, then hides the fact it's a compressed file (to save bandwidth) by compressing it again with 7-zip. No ill intent, just wanting to ensure it gets to you.

That would be my guess, but as I said, I could be wrong.
