I'd say with solid certanity; that is a chiral molecule. No Sn symmetry detected.

For right down [missing: methyl] substituent upright it would be achiral, for OH, up or down, not.

Apparently I am missing something, I don't see how switching substituents at any starred carbon can make the molecule achiral.

I agree, I think all relative configurations of that molecule are chiral. Since all 3 substituents are different, it is not possible to generate a plane or centre of symmetry.

Maybe AWK meant that if the -OH group were a methyl group the molecule would be achiral.
