It's syntactically correct.  When you redirect output, the shell
redirects it for the subprocess. It doesn't always redirect its own
output, which is where the "file not found" message comes from
(depending on the shell).  With the parens, the shell is redirecting
the output of another /bin/sh, and *that* /bin/sh is the one with the
error message.

So if you don't have a problem with the diagnostic messages going
away, go ahead and approve it.  I don't see anything wrong with it.
