I don't have an exhaustive understanding of how it works and limits data, but on my android, it essentially has two partitions, one for personal and one for work. They do not share data. In order to take and share a photo on my work Teams chat, it has to be taken either from within teams or with the camera app on the work partition. It cannot access my personal gallery. I have Teams on my personal partition from an old job that I still help out from time to time, and the same exact Teams app installed on my work partition. They are not connected in any way. The only thing that doesn't require me to put in a pin to access on my work parition are the notifications.

Most of the limitations I experience from my side are in my own access to work resources. I can't say with confidence that those same limitations go both ways. But it does seem like that is probably the case.
