Readability is not just about "understanding what is meant if you take the time". It's also about each piece of code being easy to scan and understand to find what you need. Devs have to scan whole projects to find what happens where, and there's a balance between cryptic very succinct statements and getting lost in expanded verbosity.
Verbosity hurts that by making less code fit on your screen, the code having more stuff that's needed to convey the meaning, etc. You get lost in the extra details, and have more baggage to keep in mind.
It's the difference between saying, e.g.: "Yeah", and "I am indeed craving something savory with lots of melted curdled milk and processed pork cuts, and I believe that we can immediately proceed with the thing that we were just now discussing to do".
Which is one is the more "readable" answer to "Wanna go for a pizza?".
