Well, that's great, so wealthy Americans can be sure that they'll not have to pay more than 89.9% taxes on their top income. But getting away from the numbers and back to the issue: The problem is still the same. Sanders talks a lot about making the rich pay for tons of stuff, but does not go into detail about the numbers, or how he plans to prevent the rich from leaving the country and going elsewhere, where they can get better deals. The whole "We tax the rich and then we'll have money for... literally anything (given that it's his solution for everything)!"-rhetoric just isn't backed up by any actual numbers that could be put to the test.
