I don't think those two are codeshare partners so sounds very unlikely.
Maybe he meant Sky West or one of the other regionals DBA United.
Although, come to think of it I don't think United has any smaller regional service out of AUS. I think they're all United actual flights on 737 or equivalent.
And flying out of a smaller regional airport really helps my status game with the number of segments you get with layovers. Sure you can get bit in the ass on a layover, but I guess I've been lucky as I haven't had many issues over the past few years.
