Does overflow put coolant back into radiators??

I had a similar experience with my WR426 where the radiator was low, but plenty of coolant in the overflow.
I also had this problem with my XR650R, so I am beggining to wonder if the overflow is only to catch the coolant when it gets hot. I thought when it cooled in the radiator it would suck the coolant back but I have not seen this happen.

Or can you not see any coolant at all when you look in there ?
As the coolant drops back down in temperature, I don't think there is enough vacuum in the system to fill it back all the way to the top.
(I could be wrong, my YZ doesn't have a catch bottle like the WRs.)

The tech told me to disconnect the top hose and it should prevent this problem from occuring again, additionally I did have the idle too high so when I stopped riding those few times it must of cherryed the exhaust eventually melted the hose which I could see. This hose is right behind the first exhaust connection coming from the head.
