That is not a published reference. It's speculation by the author of the article, not a part of the statement by Boeing. Heck, he doesn't even claim it uses one method or another, just speculates that either might be possible.
Also, you misquoted the author by editing his grammar. You might have fixed his typo correctly, but he also might have been intending to type something totally different. Let your source's words stand for themselves.
