They are for the women's LDB and when the new rule came out they told us to use those marks as a guide for the endline demarcation throw-ins. I actually don't know if men's "requires" those tickmarks but those are the marks we are told to use. And since almost all college floors are used for men's and women's games that wasn't a problem.

And I believe NCAA-W has since adopted the men's rule about lines of demarcation and throw-in spots.
