I think what he wants to say is that actions taken in the name of love can't be judged as good or evil. They are beyond those terms.

Good and evil as used by Nietzsche refers to the polar opposite values in Christian morality. ... Thus, when he says what happens out of love happens beyond good and evil, he means that love is a naturally occurring, instinctive, visceral phenomenon

He is basically saying any act (shitty or otherwise) is justifiable if it was done in the name of love

people classify phenomena as good and evil but an action done with love is beyond them. if you do sth outta love it is clearly not an evil but not good too cuz more than good. this is to signify the greatness of love.
