Actually, it doesn't enable the interface - that's a side effect ;)  
EMC2 has three states of being (some poorly named, but I won't get into 
that):
1) ESTOP - EMC2 will not command any motion, and it holds its e-stop 
output asserted.
2) ESTOP-Reset - EMC2 will not command any motion, but it does not 
assert the e-stop output.
3) Machine On - in this state, the machine is expected to be able to 
perform motion, and EMC2 will operate normally

Pressing F1 or the EStop button toggles from ESTOP to ESTOP-Reset
Pressing F2 or the power on button toggles from ESTOP-Reset to Machine 
On, or has no effect if the machine is in ESTOP

I think there's more information on estop and machine modes, but this 
should be a close enough approximation for now :)

I think 

http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?MazakPowerOnOff

esplains it:

... snip
When the user clicks the GUI Machine On button (or hits F2), the logic
should check other conditions such as hydraulic pressure, lube level,
spindle drive ready, servo drive ready, etc, then enable amps and begin
running.

When the user clicks the GUI Machine OFF button (or hits F2), the
logic should disable the servo amps.
... snip
