It can't read from stdin, because that might be in use:
grep foo bar* | more
And most shells open stderr as R/W, so reading from that works.
One can certainly argue that stderr *should* be write-only, and programs
using stderr for reading should probably be fixed to open /dev/tty and use
that instead. But not knowing whether it's just this one odd program,
or lots of them, I can't really say.

But don't programs like "more" open /dev/tty?
