Yes, it has re-established the coordinate system that was set on 
the machine the last time you used it.  If you had a part 
feature that was set to 3.00 inches from the home position last 
time, then that coordinate alignment is set up again, until you 
change it.  You cahnge it with the "touch off" button, and set 
some machine position to whatever alignment you now need for the 
next part.

It works this way so you can do production work from one day to 
the next without having to use an edge finder or some other 
procedure to locate your coordinate system every time you turn 
EMC on.
