The Hollywood Reporter just posted this short clip about Mark discussing the Wampa scene on Twitter:

The clip they show is from the unaltered version of the scene, and the presenter notes that the Special Edition version (she actually says the words “Special Edition”) is much more graphic. I’m pretty sure that’s exactly why they use the OUT instead of the SE for the video, but I still found it kind of neat that an outlet like the Hollywood Reporter would bother going into any amount of detail about SE differences in 2017.
I’m 90% sure they just downloaded and used this video straight from Youtube (https://www.youtube.com/watch?v=B6o2WX4crxg), which would actually make it the DSE, not the GOUT.
And I’m not super surprised, the kind of people working on these things are pop culture fans - which, for the most part, means Star Wars fans - and most fans know about the SE and the differences. Plus it was a video about a tweet so they had to add additional info to pad it out.
