Master Summoner +multiple Evolved Monster with multiple Summons

[Garzag]

If i pick the Evolved Summoned Monster feat two times and then summon one monster in the first round and another monster in the second round, does both monster have two 1 point evolutions or do i have to split them?
I think both would have two evolutions because, it says "with a single spell", but in fact that isnt repeated in the special section which is more relevant for the situation.

Evolved Summoned Monster:

Benefit: Each time you cast a summon monster spell, you can select a 1-point evolution other than pounce or reach from those available to a summoner’s eidolon. Your summoned creature gains this evolution.

If you summon more than one creature with a single spell, only one creature gains this evolution.

Special: You can take this feat multiple times. Each time you do, select an additional 1–point evolution for one of your summoned creatures. If you summon more than one creature, you can choose to apply all the evolutions to a single summoned creature, or split them between the creatures summoned.

[Curghann]

Each unique instance of casting a "Summon Monster.." spell allows you to add the evolutions.

You would add 2 1-point evolutions to the single creature summoned via the first spell, and then do the same for the single creature summoned via the next spell.

The bit about summoning more than 1 creature would apply if you opted to use the summoning list from a lower level spell to get multiple creatures with a single spell.
