Humm...
From the man page of userdel(8):
DESCRIPTION
The userdel utility removes a user from the system, optionally removing
that user's home directory and any subdirectories.
So, it won't remove an user from a group, but an user from the entire
system. No signs of removing from a group on the entire man page...
Geez... seems like I won't find what I'm looking for...

An OpenBSD user... and that's all you need to know =)
