Didn't IG-88 get married to the second Death Star and explode on his honeymoon or something?
Well if you want to get all EU on us...
The IG-88 in ESB is killed on Cloud City by Boba Fett. His boss, another IG-88, however, did that weird DSII thing that you reference, as part of his master plan to lead a droid uprising and rule the galaxy.
Guys, the EU is weird.
