I have a comment going a while back saying that NEO transformed that way to do three things: scare you away (even though that is impossible), what master said, or get killed in such a way, it makes you sooo unsatisfied and lowers your blood rage (that is, until flowey showed his face).

either that or it is a reference to super bosses in RPGs doing nothing to you (regarding damage) and the fact that they are soooo easy to kill because ou over leveled.
