I think it's a good example of understanding how people think is good for the success at the top. Out of 1000 people asking "Wtf is CTR now?" maybe one needs a precise definition usable for immediate conversion to the programming code. That's the person for whom CTR and 1/CTR difference is important. The other 999 need to understand what's this term is used to measure and where it comes from - and for them this explanation is just fine. They are not people who make decisions or calculations based on it - those already know what CTR is. They are random people that need to fit a new thing into their mental model - and they won't even notice the difference, especially given the followup explanation.
