You're probably correct on what he's meaning to say ... but I highly doubt 50% of the oil is going to leak past the threads and bypass the media. Remember when the filter is tight on the seat, the threads are messed up tight ... even if it is 1-1/2 or 2 threads worth, it's still sealing. If there was any minuscule gap in the thread lash up, it's not going to be able to flow GPMs worth of flow.
