Of course I was being ironic. The 'not joking'

fact that it really is a switcher with a linear regulator.
Which is not uncommon in multi-output switchers. Not at all unusual to
see the main (e.g. 5V) output directly regulated, but secondary outputs
handled by 78xx/79xx linear regulators.
That's not to say that the secondary outputs can't be switch-regulated.
The "simple switcher" ICs are well-suited to that application.
