You might not need to edit all project segments that are based on Fuzzy TM matches – in particular if they are very high fuzzy matches (like 99%). However, to make sure that you have edited all fuzzy matches correctly, Coach has a QA warning for Unedited Fuzzy Matches. It is easy to filter all segments so that you only see the potentially problematic segments.
