Moving picks?

[bballplayer]

If the offensive player is about to set a frontal pick for the
ball handler and is moving into the on-the-ball defender, the
ball handler moves and activates the on-the-ball defender to
move forward into the player that is going to set the pick.
Would this be called a moving pick? Or is this motion offense
incidental contact? How should this be called?

Thanks for any input,
