Sometimes you have to just have some trust in what people say.
Especially if there is no real motivation to it apart from to want to see it again and especially as this was said before we have seen the deleted material that has surfaced and been made public in 2011 and this was said in 2008 and recounted by 3 separate individuals.
I certainly never saw this version but It adds up, and I think for what information it does give up it is worth taking note and not disregarding it entirely.
Keep some of what has been said here in the back of your mind don't treat it as gospel but as an account of something that could be both remembered correctly and remembered incorrectly. But it is a very insightful account and could very well have been the proposed "LUCUS" cut not the initial Kershner workprint.
Also the note about the actual torture of Han Solo and the nodes hitting his chest. Kershner confirmed that this was removed but I guess he admited that on the 2004 edition but not as descriptive as this account tells us.
