Your conclussion starts from a flawed preconception, that being prerrequisites == stats. However, by looking at the Eclipse class entries one can deduce that the prerrequisites are powers, be it of a category or precise effect.

Also, it has been mentioned in the LN that he "trained" some parts of his PC over the regular limits (his list of known spells is almost double of what a new lv100 caster would be, he can wear 9-10 rings instead of just 2, and his strength stat is way over what a magic caster would have after reaching lv 100). Most likely that came from farming, pay items and class powers (the spell list requires some sort of sacrifice, as mentioned in the LN).

And if you want to give him a category, more than a necromancer he would be a Negative Energy master, due to his specialization in save-or-die spells and the summons being more or less class powers without any mention of being improved.

Simply put, being able to summon undeads in 3 different power tiers does not make you a necromancer (in pathfinder/D&D 3.5 for example any cleric or arcane caster who has not that magic school as forbidden can summon undeads, but only a few specialize into making them stronger or more numerous).
