Maybe because he already have awakened them ones, and now it’s just summoning on command? ^^
Possible I guess? But he could just say "Come Out" any time, not really meaning the shadows and they appear and that would really expose him.
I think 'Arise' the command for letting the soul come out of the body. 'Come out' might be the command for summoning the souls he can store.
Arise I think is when he wants to make more if he sees black shadows from dead bodies, not sure if anything else is a special command. Just "arise" so far
I thought it was "Arise" not "Come Out"
