This statement is contradicted by comments on the same announcement page describing the feature's actual behavior.

A user reported receiving a "New users interested in dialoguing with you (not a match yet)" notification, which means other users' checks were at least partially visible before a mutual match. A LessWrong team member then confirmed that these notifications existed and explained only that they were sent on a weekly basis and that the page did not sort clickers differently. That confirmation undermines the claim that checks were invisible unless there was a match.

So the accurate description is not "they can't see your checks unless you match," but rather that the system could notify users that someone had expressed interest even without a match, while obscuring exactly who it was.
