That's not a valid test of the adbv's performance. Dapat vertical yung orientation ng filter, same as it would be when installed. The adbv is usually a simple plastic or rubber membrane that falls to the bottom of the filter to block the holes using gravity and the weight of the oil itself to hold it there. If you hold it 90 degrees horizontal then the adbv won't necessarily mate to the surface.
adbv is piece #4 in this diagram. how it works should be obvious, as is the bad methodology of the test in those videos.
