I haven't had time to watch the whole video yet, but from the little I have seen I don't think your summary of what is said in the video is correct.
Although the terms 'wootz' and 'damascus' are at times used rather loosely (and perhaps sometimes accidentally interchanged) they don't say that damascus steel is the same thing as wootz steel, but rather that damascus steel is made from wootz steel (which was already widely known). Wootz steel is the raw crucible steel and doesn't yet have the pattern that you get in finished damascus steel.
You also imply that damascus steel requires impurities that are found only in ores from a particular mine not far from Damascus. What was actually said was that production of damascus steel requires wootz steel with a particular impurity (Vanadium) and that to their surprise they found that the mine near Damascus was able to provide such ore (so it wasn't only wootz steel sourced from India that was capable of forming damascus steel).
Thanks for posting the video though, it's certainly compelling viewing for anyone who has an interest in the subject.
