No, of course not. Again, you need to read everything
in context of the claims. There is much more to
Cantor's theory than this simple proposition. The OP's
claim depends on a geometrical interpretation of the
difference between 0.999... and unity. If the CH
is true, no such interpretation is possible. If the
CH is not used, the OP's terms are not differentiable.

The CH was used in my explanation to illustrate the
rules of geometrical constraint, betweeness as Weyl
referred to it. Cantor's theory teaches us that there
is no abstract betweenness, and real analysis teaches
us that limit functions produce real results. Then the
OP's proposition has no harbor--we are either talking
about measured real results, or not. Any proof of his
claim would have to incorporate measured real results,
and when attempted would necessarily show the
equivalence of his terms; i.e. things that are not
differentiable are identical.
