Cross blooded Rager / Sorcerer multi class

[UneditedMcJesos]

Hey all,
There's an archetype for the Bloodrager that allows them to choose two bloodlines (http://www.d20pfsrd.com/classes/hybrid-classes/bloodrager/archetypes/paizo ---bloodrager-archetypes/crossblooded-rager) that specifically calls out the use of another class's bloodline. "If the crossblooded rager already has a bloodline from another class, one of the chosen bloodlines must be that bloodline."
My question is what does that influence should you take a first level dip in sorcerer and choose for example, the Orc Bloodline, then take Crossblooded Rager and select a normal Bloodrager bloodline

I'd say that you need to change a bloodline to match. Since Sorcerer is the only one with a bloodline you can change to match, then you would need to change the Orc bloodline into one of your Bloodrager bloodlines.

Okay, in that case, does the quote refer almost directly to the Eldritch Scion archetype for Magus then?

More or less.
