Didn AstroFighter pilot Conroy die in the Japanese version of Season II as well as the movie, Arrivederci Yamato?
Yes. But, the American version covered up his death. Later, in Season III, when we see what is really Conroy’s /brother/, the American version simply let’s us assume he is Conroy (since they look identical). We might wonder why the Japanese producers brought in a brother who looks just like the dead Conroy. My guess is that they regretted killing the original Conroy off, and wanted the character back.
