Typical height of the polar front jet stream is 30-40,000ft, that's great for a 787 that's most efficient exactly in that altitude range. But doing mach 1.7+ you want to be much higher for efficiency, so it's entirely likely that the Boom plane will miss the jet stream.

They're talking about going against the jetstream, so that doubling air velocity means more than doubling ground velocity. If the boom plane gets to miss the jet stream entirely that only improves the situation.
