The bash man page does mentioned closing, quoting your link: If word evaluates to ‘-’, file descriptor n is closed.

@studog Thanks for checking the source! I think what happened here is I was looking at a local manpage for Bash 3, and then linked to the online documentation, which was for Bash 4. In the old Bash 3 documentation, the phrase about closing was omitted from the description of [N]>&WORD: git.savannah.gnu.org/cgit/bash.git/tree/doc/…
