Can anyone explain why this is? I've never heard a security reason for this.

Guess 1: They append either one of those characters to the password to store some form of information.

Guess 2: The characters are column separators in some form of data store.

Shit poor security? It almost sounds like they end up converting the stored password to digits, based on letters associated with numbers on a standard phone (originally 'Q' and 'Z' were omitted). I wonder if they consider 'ad4jmp' and '2ehkn7' different passwords. That would be an interesting test.
