As a general rule, locations in the Mountain Time Zone do get the west coast feed, but not always.
There are some locations that are two hours behind the east coast feed for programming and are a hour ahead of the west coast feed, and some locations are so close to the dividing line between the central and mountain time zone areas, they follow central time and thus, may choose between the east coast feed or the 2 hour behind mountain time feed. (This has been apparent to me from voting patterns tracked on Dial Idol for AI voting during that season.) It is complicated. But those of us who are trying to give a heads up about where there may be delays try to be cautious and give y'all a heads up about the possibility so you can plan accordingly.
