It's been a couple of years since I watched that episode so am just going on your description, but I would imagine the joke was meant to be that the 'son' looked so much like him, it really did have to be his - and with his phillandering, it's hardly unlikely.
I always took those final scenes to have been set in
1992 and hadn't really thought about the ages. Ultimately though, some older people are healthier and more able than younger people. Likewise, people can appear older or younger than they actually are - or are meant to be. Just looking at one's own family will often prove that. I don't recall any particular implication of ages of the Colonel or René, but I wouldn't have put them at particularly different ages from each other.
The biggest stretch is that they're still alive at all in
1992 though, not their perceived ages! I mean, I'd have estimated René as - at best - in his mid 40s when Nouvion is initially occupied. That would place him just a few years shy of 100 in
1992, and the Colonel similarly!
