It doesn't. Perhaps you only checked half of the behavior. Its internal
echo honors the \ escapes (as POSIX says it should), but it also honors
-n (which POSIX says it mustn't).
$ type sh
sh is /bin/sh
$ ls -l /bin/sh
lrwxrwxrwx 1 root root 3 Oct 1 23:21 /bin/sh -> ash
$ sh -c 'echo -n foo; type echo'
fooecho is a shell builtin
