Potency score for protected hydroxy group

As per CPCA, "Hydroxyl group bonded to β-carbon on only one side of N-nitroso group (cyclic or acyclic) then it will score +1.
Is the same principle applicable to silyl protected Hydroxyl group?

@ Yosukemino,

Would like to have your views on below query.

Hi, @sarushail,

I searched nitrosamines with β-carbon bonded to silyl protected hydroxyl group in LCDB. Then I could not find those compounds.

And I am sorry I could not find the description of the effect or mechanism of β-carbon with the hydroxyl group. @David can explain it, I suppose. The following is his presentation slide.
