Although starsan is not normally a problem if you get it in your beer, if the starsan in your your blowoff bucket was full of nasty krausen (which, if your beer was actually in need of a blowoff tube, it probably was), chances are the sanitizing power of starsan was dramatically reduced if not eliminated so it probably wasn't exactly sanitary any more and therefore probably not a great thing to get back into the beer.
I would have racked the beer anyway as you did, however I keg and force carb so I have a lot less fear of the effects of an infection... Since you're bottling I'd just keep a watchful eye on the bottles, looking for gushers, etc.
Chances are you'll still be fine, but you never know.
