My guess is that you are right and that it was needed only for the function readscreen(), used by RAND_screen() (see [1]). A quick search shows that this function was removed in pull request #1079 (merged as commit 888db7f224fe) before the release of 1.1.0, see [2]. Would you mind creating a pull request for changing the NOTES?
