The next paragraph after the screenshot is also important:
At the first sitting of the House after an election, the members of each recognized party vote on whether any or all of the sets should apply to their caucuses. The provisions only applying to the caucuses that approve them was another compromise to ensure passage of the Act. The approval of the provisions by the caucuses is binding until Parliament dissolves, after which another vote is held.
The Liberals did not vote to approve the provisions, so this can't be used to remove Trudeau.
