The pattern might be Domestic English verse Foreign English variations. At some point they need to lock the video and audio so the foreign language variations can be made. Some of those foreign language variations might use the English audio and just add language subtitles. So that’s a version A. The Domestic English, version B, depending on scheduling of producing a higher number of units to ship to theaters might permit the production team to made additional changes. So as the trend towards home release is for the removal of the topics identified in this thread, that maybe the US domestic audio mix, and the ones with the sounds came from a foreign version mix. Going to take some digging into the sources to understand better, if it can be figured out where the recordings originated. The problem that is starting to happen is the sites where they came from are starting to disappear. The ones listed in the TPP tread I tried to save the webpage where I learned of them.
