I would argue that in order to fully and truly understand some code you have to be able to re-create it from scratch. E.g. to explain weird constants, data structures, design decisions, estimations on complexity. Hence, in my eyes, the intelligence required to perform those tasks are the same.
But, there is a backdoor. Solving problems needs immense creativity. Not everyone that easily grasps a piece of code (a domain expert, savant, MIT wizard) could have written it. To my eyes, that doesn't mean that the savant is necessarily of inferior intelligence, but likely less creative in this area.
