That's probably talking about "WDS bridging", not what Don is talking

"PC" on the left side won't be able to talk to anything connected to the
right side (unless you punch holes in the "WAN" of the right-side
router). Suppose if that's your goal, it'll work fine (barring
double-NAT for the right-side devices, if that matters).
