Separate living quarters refers to living in the same house, with perhaps one living in the upstairs apartment and one living in the downstairs apartment. That is permitted even after “Separation”. When the court says that “living together” invalidates the separation, the court is most likely using the term to refer to “having sexual relations” after the separation.
By commencing to “live together”, meaning “having sexual relations together”, the parties are exhibiting with their actions that they did not intend to dissolve the marriage and therefore that calls into question the separation and all other terms of the separation agreement which you refer to, including the inheritance provision.
Generally, well-written separation agreements provide that even if the parties do get together again, the terms and conditions agreed to in the separation agreement remain valid until a new agreement is entered into.
