Because it only takes cases where there is a reason to question the Appellate courts ruling.
So of Judge Sotomayor's 150 rulings, only 3 have been overturned, so 98% of her rulings has stood the test of time.
And that doesn't mean she ruled wrong in those three cases, the Appellate court is bound by precedent, when the Supreme Court decides to overturn a precedent and set a new precedent, they wait for a case decided by the old precedent to make it's way through the process.
