I'm not sure how that is functionally different to mintplant's example?

In fish you just type 'w' hit the up arrow and then hit enter to execute or any motion keys to edit. The same number of keypresses as well.

Am I misunderstanding?

Discoverability. With fish i would have to type something that would be a good match to the command i want to re-run before pressing up. With bash i type ctrl+r and start typing and i can continue to type until it's narrowed down to the correct command.
