What if there are only two Parity Disks left?

Stupid question:

 

Consider a 4-disk Unraid Array built from 2x Parity-Disks and 2x Data-Disks. And now consider the two Data-Disks fail.

 

Will the two remaining Parity-Disks emulate both absent Data-Disks?

 

I'm pretty sure that this will happen because of different P+Q calculations, but I can't find a confirmation for this special case.

 

Thanks in advance.
