In the short term I think so (you'll see stuff in the comment history like 
"so-and-so commented on an outdated diff").  In the long run it seems to be 
discarded.  You may recall that git periodically collects garbage from the 
version history, but on a time frame so that even "deleted" material is 
preserved for at least 1 month -- see:
https://www.kernel.org/pub/software/scm/git/docs/git-gc.html

So I'm guessing that GitHub preserves this data until git collects the garbage 
from the repo.
