Does KAF2 mean that SDM only lens will focus by manual?

As title,
I doubt KAF3, i.e. DA17-70,DA*55, will not be able to AF.
Am I right or wrong?

The picture of the open mount shows the SDM connectors and looks exactly like the mount on my K-5, so I expect SDM will work (or not work) as usual

The K-01 offers full support for both SDM and non-SDM AF.

We say KAF2 because KAF3 specifically means that it doesn't have the AF shaft.
