yes, the primarchs were created using emps' genetic template, but emps did a lot of 'tinkering' on their gene codes and not one primarch was a clone of emps, which means that while it's totally plausible that vulkan got his perpetualness from emps, it's just as plausible that he didn't.

personally i'm of the opinion that emps isn't a perpetual because 1) i think it would be an almost total cop-out from gw if emps perpetualised and asserted human domination on the galaxy (which'll pretty much break 40k), and most importantly 2) there is zero information that states irrefutably that 'the emperor of mankind is a perpetual'. if the vulkan lives novel says so, and it isn't simply the opinion or belief of a character,,then i will do a complete u-turn on my opinion and will willingly accept such. but everything else is just supposition, conjecture, and hope.
