Did I cut my door frame too high for installing laminate wood floors?

I'm installing 12mm laminate wood flooring and I was following the directions about how to cut the door frames but I'm not sure I like how it looks. The directions say to line the wood floors up next to the door frame and mark 5/16 of an inch above that height to allow for expansion. Does this seem right? Will the floors possibly expand upward that much? After seeing how goofy it looked I started looking elsewhere for advice and everything else is saying to cut the door frames flush with the floor. Now the more important question, assuming I cut the frames to high, how can I fix this mistake? Caulk, quarter-round over door trim, anything other than replacing the door trim? Thanks.
