It should if it doesn't recognize the passed-in binding name. See the 
comments in the override of it in Leopard /Developer/Examples/AppKit/
Sketch/SKTGraphicView.m.

David's summary of what the default implementation does was spot on. 
SKTGraphicView shows an example where that default implementation 
isn't good enough though. It has to override -unbind: too, to match.
