I had a client about a year ago that had to deal with this same thing - was GBS positive with her first baby 2 years earlier so was told she had to have IV AB's in labour with her second even though she was neg. This isn't really uncommon despite the fact that it is not evidence based practice.
They are also often given routinely for preterm labour regardless of GBS status. I went into labour with my DD at 36 weeks and was given AB's despite being GBS negative. Again, not uncommon.
Obstetrics is one of the least evidence based branches of medicine. So much of what is done routinely to labouring women and newborns is not based on evidence, it is simply habit. It's really up to us to educate ourselves about these practices unfortunately.
