You will need to make sure the IP you assign the adapter isn’t an IP the router will try to assign to another machine or device. In dhcp services don’t assign this IP address and it’s manually assigned in the adapter config so I guess the router doesn’t know or care. I am kind of curious how traffic destined for this address doesn’t have issues though, like being received twice. Maybe I haven’t tested enough from a mix of devices on the network.

I’m at a loss as to how this would work consistently. If 2 interfaces share an IP without bonding, then only 1 would answer the ARP request from anothet host trying to establish a connection. If your system allows same static on 2 devices on same land, then other hosts talk to whoever establishes a session or answers the ARP request. I’m curious why you would want this at all?

There is no DHCP, it’s all static addresses, but there is an ARP table maintained at the router, and modern routers protect against ARP poisoning, meaning the same IP cannot have two mac addresses, and they will churn out errors. It’s also a security nightmare because many low level packet tracing tools will not work or give out false positives. I still don’t know how it’s working for you, because by all accounts, it shouldn’t.
