First, 20 years is the maximum guideline sentence available for wire fraud. The Federal Sentencing Guidelines has a points-like system (with points added for various attributes of the crime, like whether the accused took steps to conceal their crime, or crossed some dollar threshold) that heavily counts the prior criminal history of the accused. This is an egregious wire fraud case, but it's still a little unlikely that any one count will see the maximum sentence applied.
More importantly, the norm in federal sentencing is for similar charges to group, and for the longest of those counts to set the sentence. It is not the norm to serve (here) each of the "nine counts" consecutively.
