Seems to be so. I've only seen similar disclaimers on (copied) Youtube music videos before. This might be the copyright version of "I am not a [racist|homophobe|...], but ...".
Those youtube disclaimers always make me laugh. "I don't own the copyright to this", so why are you posting it then?
Obviously it's because they are confused about copyright
He could probably argue it's a parody, in which case it's not really infringement. But saying "no copyright infringement intended" is like saying "Hey, potential employers! I don't know how copyright works!"
Seems like this would fall under the satire distinction.
