Archimedean specialization of Shelah's conjecture for NIP real fields

Let KK be an NIP real field, and suppose that KK admits at least one archimedean ordering.

Archimedean specialization of Shelah's conjecture. Then KK is real closed.

This is presented as a further specialization of the preceding conjecture: any henselian valuation on a real field is convex with respect to every ordering, so an archimedean ordering forces such a valuation to be trivial. The source does not specify whether this conjectural specialization has been resolved.
