I wonder if it's related to the AVCS issues these cars had early on. The re-flash made the ECU less prone to throwing a code due to cam timing issues, but that's really just masking an underlying hardware issue. If you notice, there were some tuners who reported losing control over cam timing/AVCS intermittently on some cars.
Perhaps there was a quality control issue that got fixed on the assembly line (or on the supply-side) after 2013.
