That's not much of a shining moment in my opinion :/
Her real shining moment was against Sasori. That was the fight that showed the results of her training.
Not saying it was her shining moment but the fact people goes for flash over substance. Like which one you would consider more helpful: a person who can protect people with auto-regen or a strong person that can take down a foe, even though there's a another already. Case in point, Sakura played a support by making sure everyone is away from Kyuubi as well as planning on how to stop the chaos. It's not a shining moment but it's something that people should give more credit, but oh well, welcome to Shounen.
