I see it was not mentioned in this thread. Oh well. Again, the simple explanation would be that Pyrrha was training Team CDRL (the actual situation of how that came to be will be left to imagination), and she was confident that she could duel all four of them alone. It's most likely an attempt to gauge their abilities, or to train their team unity and coordination.

It is obvious during the Ursa Major incident that Team CDRL are not exactly on the same page, and we can interpret Team CDRL's formal stance at the library (Volume 2 Opening) that they were responding to that weakness. Hence, it isn't hard to imagine that Cardin can swallow his pride - after an episode or two of awkward proclaimation of said pride - and began fixing his Team's mistakes. He is a Team Leader for a reason.
