Seeing extra session ID,s compared to quser output

[blackops786187]

Been looking at this library to enumerate the sessions on a machine. I have noticed that for example if there is one RDP session open on a machine and I use the enumerate sessions method, I get multiple entries back alongside the one session ID that is visible via quser.exe,

Is quser filtering out these “extra sessions”. If so what would be the MS way of doing it?
