Beat me to it. 100% - 100% = 0. Actually not the best advertisement. Maybe they mean the previous version was 100% slower than the newer one.

Depends on whether seconds is the numerator or the denominator. It seems plausible to assume they meant 100%+100%=200%, and now you can open 12 documents/second instead of 6.

Why would you imagine "100% performance gain" to mean (or be intended to mean) anything other than "does this activity twice as fast as it used to"?

Not the GP, but: because, while 100% (or greater) performance difference is indeed unambiguous (assuming a delay hasn't been eliminated entirely), anything *less* than 100% isn't.
For small percentages, the two meanings of "X% performance gain" are more-or-less the same: "the task takes 5% less time than it used to" and "You can do 5% more tasks in the same time" correspond to more or less the same improvement (multiplying by 1-X is about the same as dividing by X+1 for X << 1). But as the percentage gets higher, the approximation gets worse: e.g. "the task takes 33% less time than it used to" corresponds to "You can do 50% more tasks in the same time".
Generally, we seem to have standardised on the first of those, and understand "X% performance difference" to mean something takes X% less time than it used to - hence all the comments on here.
So letting people use "100% performance gain" as meaning "You can do 100% more things in the same time" *isn't* harmless even if in that particular situation it's unambiguous, because it gets people used to using that second meaning of "X% performance difference" as well as the (more standard) first.

Yeah, it's a feature called brainreadahead ;-)

You joke, but some systems actually do have forms of predictive readahead that come close. For instance, fetching and pre-caching content that you hover your mouse over, so that it loads instantly when you actually click it.

Heh. Reminds me of when my brother (who only used his bike for commuting) went to a bike shop and they were trying to sell him on harder, thinner tires to replace his fat slow mountain bike tires. He replaced his rear tire and told me "they said it'd cut 5 minutes off my commute- a little implausible since my commute is 8 minutes." I said "you should have replaced your front tire as well, so you could arrive before you leave."
