@ellonumsk My intuition is different profiles would have different sessions, cache, cookies etc. I will try to find more from the posts you’ve linked. I will post an update if I find something else.
I tested as mentioned by @pes here- Fingerprinting: How do we know it's actually working - #4 by pes and it appears that different profiles share same session. Nice find OP, I guess you tested already 
. Maybe Pes and @Mattches can give more info.
