"Congratulations to the British Everest Expedition - Rolex - 7 Times on Everest. Finally to the Top!" - June 2nd 1953
Without the benefit of all the other details around the expedition and smith's own statements a reasearcher finding the headline above in the London Times could easily read this as a summit. Not saying Perezscope is wrong, but it's worth remembering the context of the source materials.
