You have misunderstood. Ankit Panda was simply stating that the image resolution was higher than anything that had been publicly released so far. It wasn't anything unexpected.

Melissa Hanham is a policy specialist, not a physicist or optics engineer. She has no particular expertise in this area.

If you don't believe me then do the math yourself. It's easy enough to figure out the maximum diameter of a KH-11 based on the size of the available launch vehicles. And from that you can calculate the maximum resolving power. They can play some tricks with adaptive optics and digital image processing but that doesn't add much.
