I think the point was that you accrue "hiring debt" as you stop reading details in the resume so you can get through them faster (the benefit), then stop being as detailed in the screens, again so you can get through them faster. Each step, you are increasing the debt, because it moves on to the development team to pay that debt by taking more time out for interviews.
Of course, in this case, all the benefit goes to the manager and all the pain goes to the developers.
