They remain within the same L2 domain when connected through a 10G switch that stays left unconfigured, enabling direct communication.

Additionally, in your initial comment, consumer router "LAN" ports are tied to a switch chip, meaning devices staying in the same subnet won’t experience performance drops on the router since the CPU isn’t processing it—only the ASIC does.
