Does anyone know how this works, because there seems to be conflicting information on this thread?

1. If you have overlapping stays do you get stay credits for the whole duration? I imagine I will not get double nights for the overlapping stays but do I get at least one night credit for each night that I am booked into at least one hotel? So if I have two bookings in different cities from 1 to 5 June 2025 and 3 to 8 June 2025, would I at least get 7 nights credit?
2. Will I get my points for both stays?
3. Does Hilton allow overlapping stays by 2 nights in different cities? So I want co check out of one hotel on (say) 15 June and check into another hotel on 13 June? Clearly I do not want to do this if it is prohibited.
