The 100 Units Vali received from landing the lethal hit would have encouraged her to go with a follow-up attack, but she didn't.
Something didn't feel right, and she wasn't thinking about how Rias' had suddenly turned stiff right before she tackled him with her sweep.

Cellular Supremacy, was its name.
