Why are the Rockets behind in the playoff standings even though they have a better record than the Jazz?

As of right now, the Rockets sit at 54-26 and the 5 seed in the Western Conference while the Jazz are at 53-27 as the 4 seed. Why are the Rockets below them in the playoff standings even though they have the superior record?|||Different divisions.....The top teams in each division goes 1 through 4, then the last 4 goes by records.
