Nothing on wireless involves two nodes. Each station broadcasts. It's only
happenstance if only two stations are receiving, it could easily be more.

Did you see this?

Did you see this part?

https://en.wikipedia.org/wiki/OSI_model#Comparison_with_TCP/IP_model

"The OSI protocol suite <https://en.wikipedia.org/wiki/OSI_protocols> that
was specified as part of the OSI project was considered by many as too
complicated and inefficient, and to a large extent unimplementable.[21]
<https://en.wikipedia.org/wiki/OSI_model#cite_note-Tanenbaum-21> Taking the
"forklift upgrade" approach to networking, it specified eliminating all
existing networking protocols and replacing them at all layers of the
stack. This made implementation difficult, and was resisted by many vendors
and users with significant investments in other network technologies. In
addition, the protocols included so many optional features that many
vendors' implementations were not interoperable.[21]
<https://en.wikipedia.org/wiki/OSI_model#cite_note-Tanenbaum-21>

Although the OSI model is often still referenced, the Internet protocol
suite <https://en.wikipedia.org/wiki/Internet_protocol_suite> has become
the standard for networking. TCP/IP's pragmatic approach to computer
networking and to independent implementations of simplified protocols made
it a practical methodology.[21]
<https://en.wikipedia.org/wiki/OSI_model#cite_note-Tanenbaum-21> Some
protocols and specifications in the OSI stack remain in use, one example
being IS-IS <https://en.wikipedia.org/wiki/IS-IS>, which was specified for
OSI as ISO/IEC 10589:2002 and adapted for Internet use with TCP/IP as RFC
<https://en.wikipedia.org/wiki/Request_for_Comments_(identifier)> 1142
<https://tools.ietf.org/html/rfc1142>."
