I agree with these responses.
On the first play it seems that the defender got into a tough spot and became afraid that he was going to fall hard so he grabbed the offensive player in whatever manner he could to prevent his own hard landing. That grabbing turned out to be around the head and neck, which dragged down the offensive player.
The fact is that this was excessive contact caused by the defender. It doesn't matter that he may have been trying to prevent his own awkward fall. Too bad. He is the one who decided to jump and put himself in that spot.

The second play is just a regular foul while trying to block a shot, even though the defender is fouling from behind. Going intentional here seems to be an overreaction.
