Also Leia would have been giving the order to blow up the planet she was on and coordinating the attack on Starkiller at the same time?
Like Palpatine ‘inspecting’ the Death Star Leia knows she is safe, she trained both sets of combatants. Hubris of the Dark Side. Playing both sides of a war is as classic as a planet smashing globe thing with a weak spot at the end of a trench. Vader sensed the potential and taunted Luke with it. As Max Von said she is royalty so manifesting as a giant enthroned being fits the profile too.
