But this bill would only prevent the courts from hearing any further abortion cases. Roe would remain the law of the land (that the United States Constitution grants a right to an abortion), and no subsequent case could come along to overturn it.

A subsequent case wouldn't need to overturn it. Regardless of whether somebody would still consider it "the law of the land", it would be completely ineffective. State passes law against abortion, state courts uphold it, nothing can be done about it, because it doesn't go any further than the state level.

It seems the bill specifically allows for the reversal of unconstitutional decisions:

Use by Congress of Article III regulation of the appellate jurisdiction of the United States Supreme Court and other federal courts is provided by the Constitution as a check on the Judicial Branch when it exceeds its jurisdiction.

At the very least the legislature could return the decision to the states and the SC could do nothing about it.
