Magus Eldritch Scion / / Bloodrager multilassing

[SharadW]

Hi guys. For example, we have E.Scion 3 // Bloodrager 1
Can you tell me, do their levels stack for bloodline powers progression? I can't find clear argumentation.
They have the same bloodline and Magus treats his level 3 as 'effective bloodrager level'. But Bloodrager 1 is also counts as 'effective bloodrager level'.
Can one character have two different 'effective bloodrager levels' for the same ability?

If they don't stack, how this weird combo works?
Any rules/faq?
Thanks!

There is no mention anywhere that these abilities stack, so they don't. It would work somewhat like Channel Energy from different classes does.

So, your Magus/Eldritch Scion levels give you an effective Bloodrager level with powers fueled by spending points from your Eldritch Pool, while your actual Bloodrager levels grant powers that are activated by you being in a bloodrage.

their bloodlines have to be the same choice but don't stack at all and probably will result in redundant features.
