Because each input device has its own set of tools, so there is one 
brush tool for the mouse, one for the tablet stylus, one for the tablet 
eraser, etc. So there are three brush tools but only one of them wants 
to be connected to the action - the one owned by the current input 
device. When the device changes, it disconnects the previous device's 
tools and connects the new one's.

I hope that makes sense. It seemed like a good way to do it at the time 
but there may well be a better way.
