I think so too. The higher oil pressure on the narrow side of the inlet hole causes a distortion in the flow pattern. The valve doesn't correct that. Ultimately the oil has to settle down and exit the round outlet pipe hole.

Other companies think a spiral center tube swirls the oil, and louvers play games with oil flow characteristics too. I can't see any of it doing anything, but they do.
