What happens to the approval path Project Leader –> Supervisor, if no project is selected in timesheet?

 
If the approval path is set to Project Leader –> Supervisor with any Approval Sequence and if there is no Project selected in the timesheet then the Timesheet will go only to the Supervisor.
 
Reason:
 
If there is no Project selected in the timesheet then the system will look for the second approver other than Project Leader and if he is a Supervisor or individual person then it will seek their approval, because without any Projects selected, the system will not be able to identify the relevant Project Leader.
