They don't intend to allow it, it just happens sometimes. There is some disjointedness in the systems that manage inventory and clear upgrades, so in some occasions they open R for an appreciable amount of time before the clear people into it from the waitlist. During those times it is possible to jump the list by applying an instrument on your own.
