Hey, `true' is a builtin in most shells too! ;)

 $ ssh -1 localhost /bin/echo | /bin/echo dummy
 dummy
 Write failed flushing stdout buffer.
 write stdout: Broken pipe
 $ _

 $ ssh -2 localhost /bin/echo | /bin/echo dummy
 dummy
 $ _

Note: in the last case, there is NO attempt to connect to remote
host.  First one seems to be correct to me (and only this -- all
previous examples shows ill behaviour).

Aha -- I see now why this strange question... ;)

BTW, here, on linux with bash-2.05.1, both builtins and external
commands works the same way.
