Pretty sure they didn't mean to do that.

Originally, volumes 1-3 were going to be one season, but they had to split season 1 into two volumes, which then turned into 3 due to having to push plans back from volume 2 into volume 3, some of volume 3 got filled in by Monty coming up with the Maidens after volume 2, etc.

When Gray Haddock released a parental advisory, he said that Rooster Teeth was surprised that they ended up with so many young fans for RWBY, despite the fact that the rest of Rooster Teeth's content is very adult-oriented. So, they felt it was necessary to release a warning to parents after Never Miss A Beat, telling everyone to watch the episodes themselves first from then on before showing them to kids.
