What Others Think

The description is a little misleading. usermod -G GROUP1,GROUP2,GROUP3 username is how you would add an existing user to groups.

From the usermod manual page (shadow-utils 4.1.5.1): If the user is currently a member of a group which is not listed, the user will be removed from the group. This behaviour can be changed via the -a option, which appends the user to the current supplementary group list. So no. This will not "add a user to a group". This will specify exactly what the secondary groups for the user will be. `-G` alone doesn't "add" anything.

oops, you said `useradd` not `usermod`. Sorry :)
