NBA Playoffs: Round One and Two at the Same Time?

The Second Round of the NBA Playoffs began this weekend with the Lakers facing the Jazz and beating them, 104-99 (again, not news). This happens on the same day that the Milwaukee Bucks plays against the Atlanta Hawks in Game 7 of their First Round debacle. Atlanta would win that game 95-74. Does anyone think it's odd that Round Two begins despite the fact that Round One is not yet over. True it wasn't in the same conference but the Cavs did beat the Celtics in Game One of their Round Two series yesterday, 101-93. I don't see how the NBA can't wait for the First Round to officially end. I mean heaven forbid if the Cavs or the Lakers weren't playing everyday.
