But only if it knows, from the previous run, that the requested tool is

If you have the correct code setup for manual tool change, it will stop, 
but its up to your gcode source to command the machine to go to the 
place where it has room enough to manually change the tool.  Generally, 
I just run it up to about 1/2" below the z home switch.  And of coarse 
the M5 to stop the spindle.
