I think the writer of this alleged experience is inventing things.
See #58 and #68. At NKI, you are not dumped into a unsecured area. You have to go through the same portal that connecting passengers have to go through. Everyone is in the secure area but connecting passengers have to be re-screened. Since you are co-mingled, arriving passengers are also, by default, screened. This would be eliminated if they were 'dumped' into the unsecure area.

I agree with you. Until shown specifics otherwise, I suspect this is fiction to whet the imagination of the ill-informed.
