Well I'll take a reasonable attempt. Have done a firing like this in the real world as well.

Fire fast when a few things happen, such as when energy belief and overall personality inertia has lowered of an employee where their fire has diminished for one reason or another then you should get them fired and replaced as soon as possible to not allow that to affect others on the team. This can be for a number of reasons and the signs will be clear and instead of saying "oh gee he'll turn around" just fire fast stoicly and move on. The fire fast is a very unemotional philosophy where as a leader you view the team as a chain and weakest links must be cut out and a new one placed.

Fire fast is not at all indicative of what the term entails and you can't really deduce anything from that as the right deduction is what you said, fire right after hiring! But what I think the rational interpretation is; is to fire as soon as there are negative connotations being exhibited by a team member and instead of wondering if it'll change execute an order to fix it asap. I would also say fast can mean set guidelines and expecations and transparent ways to reinstill vigor into an individual. I think fire fast has an unquantified blowback where someone who could be good( even "10X" ) is fired prematurely and they could have been someone worth multiples of their salary in output for a company but were fired for internal reasons (Your policies and docs suck).
