Makes perfect sense. Carol never wanted to be Star Sapphire, pre-corps. Any time the Star Sapphire gem came to her, it possessed her forecefully, and she'd become Green Lantern's Psycho Ex-Girlfriend. (She's not the only one, either)
Once the Zamaranians created the Corps, and the rings, they changed how it works into something that doesn't completely overwhelm and possess the barers.
When the ring came to Carol to bring her into the Star Sapphire corps, she didn't really want to accept it. And only reluctantly did so when she learned everything had changed (For the most part)

This portrayal sort of mixed up the order of things, to bring about the Sapphire Corps first. I also imagine they didn't want to have Carol be a bad guy in this series.
And just because she gave the ring back and returned to earth, doesn't mean this time was only a one off deal.
