Well Texan Sir , for me It was always the same. Online/Busy/Offline status only actualize when manually asked for another request. 
( or changing page for a search ) 
I always have that manual update for status . I was not aware that other peoples had an automaticaly update. 
Please accept my humbly regards. 
( Else, if your see a "Slaved"  Shegirl online, munualy or automaticaly, she may be happy to make you visiting the interrogation room, even is a bit more ligtned with flowers on the floor and a box of chocolate next to a teddy bear  

 )
