How is this?

Well, it is true that every member of Group A satisfies those rules, and every member of Group B does not. However, there is a much simpler rule that I had intended as the solution. So here, let me add some more members that violate your rules but which satisfy mine.

Group A:

AAVAO
AAAO
VAVAX
AVAVAO
VVVAX
VAAVAVX
VVVAAAAO
AVX


Group B:

VAAAX
VVAAO
VO
AVAX
AAAVVVO
AAVAAAVX
AAAVVVVO
AVVO
