As a first guess, bash was given the name of a file to read as a script, so it opened that file using the first available file descriptor. Since you had already closed FD 2 before invoking bash, FD 2 was the first available, and therefore the script was opened as FD 2. To me, this seems like a case of "Doctor, it hurts when I bend my arm this way." Maybe Chet will disagree.
