Looker only replaces the existing cache key when the query is complete; it does *not* begin processing a “Clear Cache and Refresh” request by actually clearing the cache, just passes a flag to not use what’s already in the cache. When the query completes, the result is placed in the cache, but if the query is killed or fails (like if you close the browser), the old cache entry remains in the cache.
