Law / UK driving license mess in Poland [72]

hi have just moved here from Uk, have received form from DVLA to renew my photo. They told me i should get a Polish licence as i am living here and can swap back to a uk licence when i return to uk. is this adviseable?

They also said if the polish authorities 'dont mind' about the photo expiring then i coud still use the licence as technically expires when im 70! how do i go about finding out if this is the case? and if not getting the form? Thanks!
