This issue sounds to me like the cache wasn't properly cleared. Importing a new file with the old file name would then accidentally re-use the old (low-res search-optimized) cached copy. And yes, like the author suggests in the workaround, it's usually a good idea to change the filename. That also helps communicating that there was a change to your team members. But if overeager caching is his biggest complaint, I'd say Avid is doing an excellent job ... There's so much more that could go wrong when handing TB-sized videos with GPU filters in real-time.
