Just to clarify - TC does only mean twin-engine EOLs are not practiced in the real aircraft. His previous job in a FFS for the mil gave him lots of time to see pilots carrying out EOLs there (I should know, he flamed out both engines on me enough times)
Practice double engine failures/PFLs are a staple of twin-engine helicopter training but will terminate in either an overshoot/go around or a full flare recovery to the hover/hover taxi.
Any training is better than no training where EOLs are concerned.
