A bag is different things to different photographers. Some don't ever use 'em, others have vast collections for different outing scenarios they've come to enjoy.
I'm always putting the camera back in the bag between shooting - but that was a habit picked up from hiking. A camera dangling from the shoulder or neck is easly knocked about tthe sort of hikes I'd frequent. Often the bag is only partially zippered for quick access, though the strap is left dangling outside. But basically, it's protection for my style, which have carried over even when not in the middle of the woods.
You'll come to what works and is suitable for your habits as time/experience will dictate, regardless of how others utilize the same gear conveyances. There's no rules to follow. Unless you're somehow severely limited mentally - trust yourself and your own experiences.
Another habit I had with toploaders at one period was to sling it across the torso and turn the bag upside down. It suited the load/pack and scrambling I was involved with during that period. Looked stupid, and once when I failed to fully close the zipper. . . not something I'd recommend, but an example of an individual issue overcome by using the bag in a non-conventional manner.
Like I said, you'll find out soon enough if that bag suits you, or how you find you make it suit your own habits.

You'll have to ignore the gallery's collection of bad compositions, improper exposures, and amateurish post processing.
