"When the Parliamentarian says some provision violates the Byrd Rule Joe Biden as President of the Senate can overrule and it takes a majority vote to overrule Biden. "

That's right. And, it actually takes 60, not 51 to overrule Biden and sustain the ruling by the Parliamentarian.

This, of course, presumes that Biden would overrule the Parliamentarian. That would be unprecedented in the 36-year history of the Budget Reconciliation process. And, Humphrey was the last Senate President to overrule the Parliamentarian on any business.
