Like Rofl, I've been told once that it's because of double redirects -- the old username after all redirects to the new username. Renaming again would render all edits under the first username as double redirects. It may have several reasons though, and these we name could be among them.

As for alternate accounts: I use User:Ethear to edit in MonoBook skin, and User:Botalu is my bot account. However, there are only few wikis where I edit with both "human" accounts; mostly these are my own wikis, where I wouldn't get banned anyway. It isn't against Wikia's rules to do, though there may be local policies that are against multiple accounting.
