"Bi" means the single bulb provides both the dipped and high beam.
Before the advent of bi-xenon mechanisms the xenon would remain in the fixed dipped position and a second halogen beam would be needed for the high beam. A second xenon bulb isn't really viable due to the warm up time needed when switched on - that's why they're not used when you flash the headlights.
