So far, all the examples in the PEP have the exact same coverage with and without assignment expressions, with a few exceptions where coverage is *improved* by them (where the alternative is to duplicate a function call). By combining multiple lines into one, we also ensure that all of it is executed exactly once, instead of having conditional execution.
