On the demo page, if I slide the hue selector up or down and then immediately go to the saturation selector and try to drag the little circle around, it just keeps moving the hue selector up and down instead. I have to explicitly click somewhere away from the little circle in order to break the "bind" from the hue selector.
The reverse is also true, if I drag the circle pointer around the saturation box and then immediately try to start sliding the hue selector, my cursor is still bound to the circle pointer, and it just jumps over to where I'm at in the hue selector.
