How does Integromat Sleep module work?

Hey, guys! A complete newbie to Integromat here.

How does the Sleep module work between different scenarios?
Let’s say I have a scenario with a Sleep module of 300s. Will the 2nd scenario wait for the 1st scenario to finish its Sleep module?

In my case, the 1st scenario is when a new record is created in Airtable → send notification to Slack → then after it Sleeps for 300s → it searches any status updates were made in the same record with the same record ID.
But what if I I want to delay the module for 1 hour instead of Sleep (300s), will my 2nd scenario wait 1 hour too?
