Loremaster and other wizards of the same lore

So the rules for picking spells state that the same spell cannot be generated more than once (apart from signatures and bound spells).

So let's say I have Manfred Von Carstein as my general, with the loremaster rule for VC and death magic. Does this mean that any necromancer that I take will only be able to generate signatue spells, regardless of their level?
