It's also there for proof in instances where a derogatory or otherwise very cruel post is made, and reported. If the offender quickly edits the post and there's no mark telling when the edit was made, the mods/admins wouldn't have any proof of it happening at all.
Whereas:
-User A posts something terrible at 4pm
-User B reports this at 4:10pm
-User A edits the post at 4:15pm
This'll show the user covering his tracks to the admin team.
