You have it exactly, Serge. The MAC address is guaranteed to be unique on the planet, but only the local network needs a MAC to be unique. A router needs a MAC to be unique on each network it can directly see.
Entering a MAC into the configuration for your network card is often called LAA (Locally Administered Address); using a custom MAC is uncommon, but certainly not rare. Mostly I see this being done on firewalls or a new home-user firewall box to alleviate the bother of going to the ISP to register a new MAC address, thus letting the user keep the same IP they had.
