For the most part, there's no reason to change groups.  When you log
in, your session is considered a member of all the groups it is
defined to be in (up to some number I can't remember).  The common
usage method is "I just added you to the group, Bob.  Log out and log
back in."

Why is newgrp there?  Two reasons.  One, to change to a group you
aren't defined as a member of, but have the password (who ever
thought THAT was a good idea!).  Two, to get a shell in that group
without logging everything out.
