The post explicitly says:

"This means that the Senate has now made the tax reform bill a win for those who work in startups instead of a loss."

Not the provision about options - "the bill."

So he's clearly saying that the bill as a whole is better for startup employees than the current system. GP point is that the bill may now be better from one single perspective but on the whole is still much worse than what we have today due to other issues.
