During turnaround there is only a small time window between AZ786 arriving from Milan after all the passengers and baggage have been offloaded, but before preparation for the return flight, and when the aircraft is clear of ground crew and vehicles.

Pictured taxying out for a rw16R departure. AZA had two flights that day (the other one was operated by a 763). One flight to Rome and the other to Milan, I presume the 777 was going to MXP.
