Simple "git checkout" or "git checkout " don't tell me that i've done a mistake

That is a designed behaviour.  You did nothing wrong.

Besides, that is a way people who use "checkout -t -b" to create topic
branches check their branch status.  Pay attention to what the last
command does in the following transcript.

    $ git checkout master
    $ git checkout -t -b side
    Branch side set up to track local branch master.
    Switched to a new branch 'side'
    $ git checkout master
    Switched to branch 'master'
    $ edit ; git commit ;# on 'master'
    $ git checkout side
    Switched to branch 'side'
    Your branch is behind 'master' by 1 commit, ...
    ... time passes ...
    $ git checkout
    Your branch is behind 'master' by 1 commit, ...
