I don't think so - she is getting to the age when she will rememeber this behaviour and what you did about it, so hopefully it may help to modify her behaviour in future - particularly if you remind her of what happened and how you always so as you say.
She is exactly the same age as my dd - they are soooo funny and sweet and soooo fecking annoying as well
Me: 'DD calm down! Take deep breaths! Watch me, I'm doing it!'
DD: 'NOOOOOOOO! I can't calm down! I! AM! ANGRRRRRRRRYYYYYY. AAAHHHHH!'
And so on, and so forth for quite some time. It's a different type of rage to the 'little' toddlers. She is quite able to express herself and explain what her problems are - its just the sheer bloody ANGER when she can't get what she wants. Not all the time - and can usually be predicted to do with tiredness or hunger.
Actually, I am a moody cow if I am tired or hungry, so perhaps this is my punishment...
