Every distribution that I have used in the past has assigned a User,
for example 'computation'. in my case and has automatically put the
User in a Group 'users'. I noticed that in Debian both the User and
Group are the same, i.e., 'computation'. My question is why?
Why not ;)?
"users: While Debian systems use the user group system by default (each
user has their own group), some prefer to use a more traditional group
system. In that system, each user is a member of the 'users' group." -

It's your freedom to setup your Linux as needed. PolicyKit, su, sudo,
groups and permissions etc..
Note, that groups with the same name, for different installs, could have
different IDs.
id -a
does show you group names and IDs, valid only for the install you run
"id -a". You might have noticed that some groups are named abc on one
install and if you list a directory from another install or live CD, the
group names change to xyz.
