I think the Select Points tool and the Bind Points tool are intended to function in a similar way, but they don't. Deselecting points works slightly differently.
When using the Select Points tool and holding down the ALT-OPTION key, you can deselect a particular point by clicking on it. This doesn't work with the Bind Points tool. When you hold down the ALT-OPTION key and click on a point that is selected, all the points become deselected. You have to hold down the ALT-OPTION key and draw a box over a point to deselect it.
