Mastering Bitcoin: Advanced Scripting Question At the end of Mastering Bitcoin Chapter 7. https://github.com/bitcoinbook/bitcoinbook/blob/second_edition/ch07.asciidoc#complex-script-example

They ask this question in regards to the script:

How do the partners "reset" the clock every 29 or 89 days to prevent the lawyer from accessing the funds?

They 'reset' the clock by moving the funds to a new output before the period ends.
