He said he checks messages if they're sent directly to him. That's perfectly reasonable and I'd wager everyone on this thread does exactly the same, not caring too much about chatter not specifically related to them. I assume no one here has 10 different people DMing them questions or new stuff to do. I read his comment as he doesn't check Slack all the time unless someone mentions or DMs him. Your scenario doesn't happen in that case.
