The source MAC changes everytime the IP packet moves through a L3 device. Even in Multilayer Switching (MLS), where an Ethernet switch moves the packet across L3 boundaries on behalf of the router, it re-writes the source MAC to that of the router so it looks as if it traversed the router. A L2 network is entirely self-contained. There is no significance of a MAC from on L2 network to another.
