Good catch, I never noticed that. Here's two brief mentions I found on Google, and on the S.A. parks page I could see it was acquired in 2003 but nothing's been done with it. My guess is it was purchased almost as a city greenbelt, not intended for use but to prevent development? I really have no idea.
Brief mention of it as a natural area by Helotes Park Terrace/Park at French Creek:

"Los Reyes Canyon is a single-family gated subdivision with 204 platted lots and private streets located immediately northwest and adjacent to Helotes with Iron Horse Canyon Park directly to the southwest."
