Eidolon and casting summon monster spells

[Telrathel]

ok so my question is simply, by using the Eidolons evolution ability to give yourself Sorc/Wiz spells as SLAs can you take summon monster as a spell for that? I would think yes however I know a summoned creature can't summon creatures as part of the "summoned" template.

from reading posts from the previous playtest however, I remember there was a discussion about Eidolons and the Augment Summoning feat and I believe it was decided that Eidolons don't count as a summoned creature for that feat. So from my understanding if thats correct than, Eidolons should have no problem with casting summons.

Under the Eidolon section it actually says it's "treated as a summoned monster", which (as far as I can see) restricts it from being able to summon things itself, however, since it's not summoned from a "summon" spell, it's not benefited from Augment Summoning.
