Mosh implements a delta algorithm between the server's buffer and the client's buffer. This means if packet loss is occurring, to sync back up, the server only needs to send the delta of its state to the client.
SSH, on the other hand, is stream-oriented, and will replay everything that has occurred, even if the resulting changes to the display in the end are minimal.
It's similar to how something like VNC functions compared to the X11 protocol. The VNC protocol is more efficient and tolerant of lossy or low-latency connections.
