(assuming I know a route), the packet may be received by that machine
on the interface in the 192.168.1.0/24 network.

Even if I don't know the route, if I send my packet to my default
router, say 192.168.1.1, it may know that 192.168.2.10 and
192.168.1.10 are the same machine, so it will send the packet to
192.168.2.10 to the interface assigned 192.168.1.20 since it has a
direct path to that interface.

Last time: that is NOT the case for me. My interfaces are in DIFFERENT IP
subnets.

As they were in my example, 192.168.2.10/24 and 192.168.1.10/24 are in
different IP subnets.
