Ah I see, I think the angle, pose and how it flexes also affects how it gets positioned. To be fair most photo references show it bulging above the Vastus.
On this photo for example, it seems to be at different heights on the left and right leg.

I think what is clear at least is how both Vastus are the highlight of the upper front.
