I understand the reason behind the cache not updating if the GUID hasn't changed. However, in my case, the AD Security group in question had been in place and had not been renamed in months. The KIX script was successfully recognizing that group without any issues. Suddenly, out of the blue, that group was no longer in the cache, that's why I'm questioning the sporadic behavior of "INGROUP", and whether there may be another explanation as to what may have happened.
