When creating multiple WiFi clients, must they be in seperate "Interfaces"?

Installing and Using OpenWrt

I am running v23.5.2 and have created two WiFi client connections to two APs. Like this:

During the setup, each asked for an "Interface":

In the above, "left" and "right" are my creations. But what is the information I need to know, to make an informed decision on how to fill in the Network Field?
It seems that:

  1. I can't leave them "undefined"
  2. I can't have two clients in the same network (despite the image above suggesting I can! If I hover over the WiFi icons, the pop-up reports the same information for both?)
  3. I can't select "lan"

What role is this Network field performing?

2

Are left and right connecting to the same uplink?

3

Does this mean NO?

"left" = phyo-sta0 and "right" = phy1-sta0

This does not look right, no firewall zone assigned at the two sta interface.

Due to the way that layer 2 packets move on wifi, a regular (AP-STA) wifi client cannot be bridged to anything. It must be alone in a dedicated interface and routed.

You can use a package like mwan3 to control the routing to multiple Internet connections based on load-balancing or failover rules.
