As far as I can tell, he's mixing units (or scales?). Here's my version.

At 95% certainty, you have 95 people saying "yes" and 5 people saying "no." At 99% certainty, you have 99 people saying "yes" and 1 person saying "no."

While that is 5x improvement in uncertainity, it's also only 4 more people, a 4.21% improvement in overall "yes" count.

I can't see how comparing an N in 20 number to an N in 100 number makes sense. IANAS.
