From the website.

1500 hours total fixed-wing time as pilot-in-command (PIC) or second-in-command in multi-engine turbo-prop A/C or jet A/C or combination thereof, including a minimum of 1000 hours total fixed-wing pilot-in-command in multi-engine turbo prop A/C or jet A/C or combination thereof.
Note: PIC for this purpose is defined as Captain/Aircraft Commander of record, not simply the sole manipulator of the controls.
Note: FedEx considers only pilot time in fixed wing aircraft toward minimum qualifications. This does not include simulator, helicopter, flight engineer, bombardier, navigator, RIO, EWO, WSO, NFO, or Special Crew.

so you can see FDX makes a difference between single engine jet and turbo prop.
