Userelationship Path // CrossFilter

Hi there,

So basically I want to use, the username on AspNetUsers (lookuptable), for a slicer. The goal is to perform a calculation on Ticket_ Status_Hist (where the red and green line end). The green line path is physically inactive, the red path is physically active.

I cannot go with the red path because AspNetUser[ID] is related to Tickets[AssignUserID], and on the Ticket_status_hist, the calculation may involve other user that is not directly assigned. 

So I used Calculate (userelationship) to follow the green path. Do I also need to use inside calculate a cross filter (AspNetUser[ID],TicketAssignUserID, None) to breakup the possibility of the slicer going both ways or is it unnecessary because Power BI "understands" I want to go by green path.

Average response time=
CALCULATE (
AVERAGE ( Ticket_Status_Hist[Tempo_útil_Criacao_Update (min)] ),
USERELATIONSHIP ( 'Calendar'[Date], Tickets[DateUpdateFromNew] ),
Ticket_Status_Hist[Ranking Updates] = 1
&& Ticket_Status_Hist[TicketStatusOld] = 1,
USERELATIONSHIP ( AspNetUsers[Id], Ticket_Status_Hist[UserId] ),
CROSSFILTER ( AspNetUsers[Id], Tickets[AssignUserID], NONE )
)
