No. All of these videos show the same part of the flake being repelled by both sides of the magnet, as well as other videos showing that the sample does not attract.

I'm afraid we are not seeing the same, then. In this [0] video I can clearly see a different corner of the flake being repelled at 2:07 ~ 2:13 versus 2:27 ~ 2:30.
However, I agree that the other videos people like you have posted on this thread show materials that are not ferromagnetic.
That does not disprove my statement. As I noted in my more in-depth breakdown, compare 1:55 vs. 3:03 - you will see the same corner being lifted despite opposite sides of the magnet being used to lift it.
