In our case, you have a bevel which is being pressed so hard that the edge rises off the stone, and you end up honing behind the edge. If your pressure was constant, you would produce a flat bevel behind the edge, and that bevel would have a steeper bevel angle. If you vary the pressure, the bevel behind the edge bevel is rounded, because you have a series of bevels. As you reduce the pressure (theonly way to affect the shape of the new bevel), you create a bevel closer to the edge with a larger bevel angle, the largest being the original bevel. That is a convex or outwardly bowing bevel.
