git-annex-5.20150522: doc/forum/Ambiguous_repo_names__63__.mdwn

The output of `git annex info` includes this:

 	34xx3351-xx14-4039-6xxx-xxx9x5xxxxxx -- wx550 (wx312)
 	9x9x07xx-x6x9-464x-7x5x-x3xx42xx7x70 -- wx550

What does this mean? Do I have two different repos both named wx550?
What is wx312?
