Expanded Arcana and Crossblooded Archtype

[Agoz]

I'm planning on creating a crossblooded sorcerer, however I know that the spells known by the sorcerer decreases by one for each spell level, meaning that normally the sorcerer would not be able to for example cast level 2 spells until level 5 even though it has spell slots for level 2 spells at level 4. My question involving Expanded arcana is this:

Can expanded arcana be used to learn (not cast) a spell with a spell level higher than a sorcerer can normally cast? For example, could I learn a level 2 spell at level 3 using expanded arcana in order to have something to cast when I start casting level 2 spells at level 4?

Here's the description of expanded arcana for clarity:

"Expanded Arcana

Your research has revealed new spells.

Prerequisites: Caster level 1st, see Special.

Benefit: Add one spell from your class's spell list to your list of spells known. This is in addition to the number of spells normally gained at each new level in your class. You may instead add two spells from your class's spell list to your list of spells known, but both of these spells must be at least one level lower than the highest level spell you can cast in that class. Once made, these choices cannot be changed.

Special: You can only take this feat if you possess levels in a class whose spellcasting relies on a limited list of spells known, such as the bard, oracle, and sorcerer.

You can gain Expanded Arcana multiple times."

My reading is unless you are picking two spells with expanded arcana, there is no limit to the level of the spell learnt, even if the caster could can not actually cast the spell learnt due to caster level.

I don't think you could take this as a 3rd-level sorcerer to learn a 2nd-level spell. The number of 2nd-level spells known at that level isn't "0", it's "-".

I could totally be wrong, though.

You need to be able to cast a Spell to learn it with this feat. But if you are crossblooded and have a level dip so you get feats at even sorcerer levels then i think you can get a Spell of the level where you have slots but no Spell known yet!

I was kinda hoping for a concrete ruling, like a quote from a book or something. Sort of a "A character cannot learn spells of a higher level than they can cast" type reference with a page number.

Under the wizard recording spells from another wizard's spellbook it is similarly vague about whether or not a wizard can learn spells they cannot cast yet. In that it doesn't say that a wizard could not.

I haven't been able to find anything else on learning spells outside of normal level gain, but then again I'm sure I could be missing something.

I am around 70% sure that wizard can scribe spells of higher level that he cannot cast into his spellbook. In a way this is learning spells for a wizard. It might be completely different for a sorcerer tho, since his way of knowing spells and learning them is more natural.

Those 2nd level spell slots are still not completely ignored for a crossblooded sorcerer tho. You can use them to cast first level spell still and/or to cast metamagiced versions of them.
