I don’t think of them as some kind of anti-slip device but a locator. I suspect that the manufacturer of your bike intended them for the same thing.

Even if the stop is intended to act as an anti-slip device, using the point of the heart to keep the clamp from slipping makes no sense. You’d want the most contact available which means the top of the heart which provides to points of contact vs one. Bottom line: mount on top.
