Campaigns with offline blocks

Your software
My Mautic version is: 4.4.8
My PHP version is: 7.4.33
My Database type and version is: pdo_mysql 8.0.28

Your problem
My problem is:

Actually what I have is apparently not a problem, but something that is expected.

In a campaign, it is possible to leave the blocks (Desition, action, conditions) with no connection between them.

I understood that a connectionless block is not executed. Recently, out of the blue, I saw it running, and I thought it was a bug.

But researching about, I found this: Campaign Builder Connections

So I would like to confirm, is this really expected? In campaigns, disconnected blocks still run.
