It doesn't minimise DoB leakage at all.
Any application (inc. web site applications, there will no doubt be some HTML API in time for this) that can get the age category 'signal' can just store 1 instance of the tuple of (category indicated, date last requested) for each user and then just note when a fresh 'signal' differs from the stored - the DoB is within the range [date last requested, current date]. So a popular 'application' for a given user who is under-18 has 1 or more chances to acquire the user's DoB down to a fine granularity (to the day potentially). And popular 'applications' with large user-bases will be able to build up databases of DoBs that are correct down to the day for large numbers of people.
