Just curious, but what directed your 'usermod' question to shellutils?
'usermod' are other folks.  But I can answer your question anyway.

'usermod' and others set up the /etc/passwd and other files.  They
don't actually change anything in process space.  Those files only
have effects when you log in.  So to make those other groups take
effect you need to log in.  Usually that would mean that you need to
log out first and then log back in.
