Not only does it double check both hardware units, it double-checks the software, potentially in an fft length not run on your hardware before, which might show up new issues.
(I'm currently running CUDAPm1 on multiple gpu models on an assortment of fft lengths each, and finding interesting behaviors that differ model to model. CUDAPm1 was derived from CUDALucas, so some of it may apply somewhat to CUDALucas also.)
If you are running prp there is probably no point because errors will be detected. If it detecting errors you should worry.
