Quite simply, a ban is always issued with a time delay, so it doesn't matter if you haven't played for a week.

For your understanding, when I logged into my account, I was initially not blocked, but as soon as I logged back in, I received a notification about the block even when I wasn't logged into the game.

Doesn't matter.

Doesn't it matter that a player without cheats gets banned for no reason?

How is it that after I re-log into Steam I immediately get blocked?

You won't get banned for no reason if you get a GAME BAN.

Because that's when the penalty was activated. I can't tell you more about that, since Valve understandably doesn't allow anyone to look into their system.
