Some things: Draugr also bleed when you hit them in Skyrim, but they are undeniably undead. I do not remember seeing them reproduce, could you provide an example? Also, I think by undead (at least for vamps) in-game you are sort of "frozen". What I mean by that is that you have stopped aging, heart probably stops with blood still in your veins, etc. AND, I guess you could throw sperm in there saying it just stays. Now technically speaking this vampire is not alive but in a state of un-death. Undead meaning not alive, not dead. I do not see anything wrong.
