In the T10/12 we would normally have the command eject set to dual (either seat could command the other) other than the initial OCU press up (VTO/VL) sorties where it would be set so that both seats could eject independently. The short delay between seats in dual meant that the front seater (who would be out 0.4 seconds after the rear) wouldn't make it if the engine quit in the hover, so better to chance a simultaneous ejection with each for their own.
Can't beat sitting on pillars of jet thrust.
