Frist admits to his own filibuster and it is not unConstitutional

Think Progress article - Senator Chuck Schumer, on the floor of the Senate today, asked a question to Senate Majority Leader Bill Frist: "Isn't it correct on March 8, 2000, my colleague [Frist] voted to uphold the filibuster of Judge Richard Paez?" Frist responds: "The president, the um, in response, uh, the Paez nomination - we’ll come back and discuss this further. … Actually I’d like to, and it really brings to what I believe - a point - and it really brings to, oddly, a point, what is the issue. The issue is we have leadership-led partisan filibusters that have, um, obstructed, not one nominee, but two, three, four, five, six, seven, eight, nine, ten, in a routine way." In other words, a senator who filibusters one nominee is not wrong, but a party who threatens to filibuster a handful is? If the filibuster is unConstitutional, should not Frist then be kicked out of the Senate for not upholding his oath when he was sworn in?
