One thing is true, and you are right with it: Chaldea's summoning system is different from Fuyuki's summoning system.

On the other hand, another thing isn't true. Cú Chulainn Caster (that Cú Chulainn we saw in the episode) isn't from Chaldea's summoning. He was one from the seven Servants summoned by the Fuyuki's Grail. And that war was a normal war from the beginning until Lev intervened. And we can't even said that Lev intervention affected the summoning system or Cú's memories, because Caster already told how the war was a normal one until suddendly all the Masters dissapeared and Artoria become Alter.

So... Yeah, it can be logic that a Servant summoned by Chaldea keep his/her memories (still, I keep thinking it goes against logic because it means that each summon can modify the complete soul of the hero in the Throne of Heroes), but it isn't logic how a Fuyuki's Servant (EMIYA, Cú Caster, Artoria, Medusa Lancer, Cursed-Arm Hasan, "Darius III" Rider and Heracles) can keep memories from other wars.
