What you're seeing there is what the server declared the content to be.  Bro ignores that value and sniffs the content to try and identify it.

You have found a weakness in our shockwave detection fingerprint though.  I'm going to be doing a commit into master soon that improves on our Flash detection (our signatures don't detect LZMA compressed flash files).
