my understanding of the matter is that companies do this so that you can't turn around and say "hey, I thought of this main idea of one of your major components in my off time. $$, please.", especially after you've left the company. even companies that have draconian sounding policies often have reasonable procedures for release and common sense policies around commenting on the Internet.
if you're concerned, just make sure you ask at your interview. it will make you sound good and stands as a reasonable bozo filter with regard to the company, for your sake.
