He runs a compact and normal cassette. But "junior" rules don't allow any cog smaller than 14. So he has to block out the 13, 12, 11. If he used the 13 with the 50 front, that would still be higher than a 53/14, so it is not allowed. Some of this is guessing on my part regarding the details, but that is the general idea, so-called junior gearing.
