There exists a collision bug where the check used to prevent Sonic from clipping on top of a surface he's too far below from isn't done if he's moving horizontally in the air. This can easily be seen if you put a solid object on a top solid surface and hit it from the bottom.

There are 4 collision modes while airborne, 1 for each cardinal direction. When he hits the rock, his Y speed is cancelled out while still moving right. Since he's technically colliding with the floor and the check isn't done, he clips on top of the surface, right into the rock.

This is what the missing check does, which is present when mostly falling downwards and less horizontally.
