When you cut off a slasher, you're moving towards that player. Note: the rule doesn't say move forward; it says moving towards. You must stop the motion before contact occurs (that's what I mean by "set"), and the center didn't. And since she didn't, she is liable for the contact.

The movement I see is pretty much at a right angle to the path of the dribbler.
Legal guarding position was obtained, and the dribbler created the contact.
