The effect may only be visible with a full cache. According to devtools, the deferred script appears to block parsing, but this isn't what deferred scripts are supposed to do. Is this devtools misreporting, or is it really blocking parsing? Also, it seems to block rendering, which is surprising, but I remember pmeenan@ mentioning this may depend on the elements that come before it.
