Occultist and Psychometrist Question, what counts as occultist levels?

[Strong9510]

Perhaps similar questions have been answered regarding levels in both hybrid and the parent classes. I have not found anything to answer this type of one however.

I am considering an Occultist dip for Implement school in necromancy and transmutation. I would take the focus power Necromantic Servant. If I were to change to a Vigilante:Psychometrist:Avenger and take the implement school Transmutation, would my Vigilante levels stack with the Occultists for the base power Legacy Weapon? If I were to choose instead to take the implement focus necromancy, would my levels in vigilante count for occultist levels in regards to the Necromantic Servant?

Possible relevant text from Ultimate Intrigue Page 59:
The psychometrist treats his vigilante level as his
occultist level for purposes of determining how his
implements’ focus powers work, and for determining at
what level he may choose certain focus powers.

They don't stack since it doesn't say it does. You have two separate pools. Can't use both at the same time on same item cause they'd count as same source.
