I don't believe Ron's intention at the time ran much deeper than the impishness of doing a Monty Python and the Holy Grail ending. I hardly doubt he had "thoughts" for where he might have gone from there, and it is intriguing how that rug pull encourages you to re-examine the games' fourth wall humor as if it was conscious foreshadowing, but I think by and large he just liked the idea of a wild swerve to be answered for only when/if the time came to do so.
