Given that all of your sectional completions would be linked to overall planned Completion, the planned Completion will now be at the end of your 2nd planned sectional completion and hence the critical path now on the project.
Terminal float for each sectional Completion and the overall Completion Date is owned by the Contractor - so again programme logic should drive/show the correct answer.
Point of note in your question - this is quite poor drafting as the last sectional completion did not need to be one - it should just have been the overall Completion Date.
