Client Isolation (sometimes AP Isolation for some reason) is a technique found in most network equipment, access points and home routers dealing with wi-fi. When used, clients won't be allowed to communicate, they'll be invisible to anyone but the AP, or router, they are connected to. But being connected to a wi-fi network isn't a requirement to sniff wireless traffic. It's possible to also monitor traffic, and AFAIK an APs internal ACL won't matter much in that regard.
