The point is to leverage human pattern matching so you want short-ish figures with large differences.
Each hex digits is 4 bits, but each emoji is 10 bits, a 128 bits key is 13 emoji which is significantly more eyeballable than 32 hex digits, and chances are you'll notice EGGPLANT being replaced by CAMERA in 13 pictures easier than you'd notice B being replaced by 8 in 32 characters.
