That happens because help2man without arguments will output to stderr.
Add --no-discard-stderr, and it will just work. Or try with a program

It does do the trick.

Or you can read the full output of the command you pasted:

| algernon@luthien:~$ help2man -h "" help2man
| help2man: can't get `' info from help2man
| Try `--no-discard-stderr' if option outputs to stderr
