Im not sure what there policy. It would be interesting to see what their operations manual says. Although I know many airlines are reluctant to offer PIC Under Supervision.
Nonetheless they are certainly not going to give it to you during your first 1500 hours of MPL training. Therefore you will not have the requirements to convert your license under ICAO.
On the flip side 1500 hours of Airbus time is golden and the laws world over are changing. So there are risks but this is the fastest way of getting jet time with a reputable airline.
