That's correct. You have to do it that way or the system in recovery mode can start to consume the new segment file before it has been completely copied over yet.
Does pg_standby take care of this by checking file sizes or the like? In my testing with scp, we never experienced any problems, but I wonder if we were somehow "just lucky."
