gearchange question

I'm trying to implement the gearchange hal component with the gs2 component to change the gearing and direction when I change gears on my supermax knee mill.  I have hal files setup and I created 2 pyvcp toggle (checkboxes) buttons to toggle the gearchange select pin and the gearchange direction input pin:

net gearchange-select gearchange.0.sel
net gearchange-select pyvcp.gchange-chkbtn

net gearchange-dir => gearchange.0.dir-in
net gearchange-dir <= pyvcp.gch-dir-chkbtn

Also, I set the gearchange reverse to true (1):
setp gearchange.0.reverse 1  #reverse direction in 2nd gear.

My question - is the gearchange reverse automatically 'done for me?'  I guess I need some sort of hal network (like an or or mux) to change the following directions based on the gearchange.0.dir-out pin??:
net gs2-fwd spindle-vfd.spindle-fwd <= motion.spindle-forward
net gs2-rev spindle-vfd.spindle-rev <= motion.spindle-reverse

I've posted an abridged hal file here:  http://pastebin.com/Qtb3AJMm
