Ancient Cyclops placeholders in South Ro?

[Thulghor]

Been trying to get the ring for the boots off of the AC for a while now, and I finally see the AC spawn again, but I was barely beaten there by Upenu this morning. However, something occurred to me. I slacked on the placeholder killing, and was just kinda chilling, yet the AC spawned. All the placeholders were up. Like, all of them. The mummy, the other mummies, the roaming dervs, the desert madmen and other madmen, pretty much everything on the wiki list was up. The zone was pretty much refreshed.

Do the alleged placeholders even matter?
