The titles for these roles are not "postdoc" though, that's his point no? The role "postdoc" doesn't exist, at least in any institutions I know.

They then call this a "postdoc" position to indicate that you need a PhD to be hired, but the contracts and conditions do not specifically cater towards people pursuing careers in academia.
