 In baseball, runs are rare and outs are common, but in cricket, runs are very common, outs very rare. So when you get the chance to catch a ball, to get a batsman out, you need to catch it. Oh, and that was an easy one. The batter, Warner for Australia had 10 runs at that point and he would have been out. You hit until you're out. You accumulate runs until you're out and he could have got them out and he didn't. And guess what? Warner went on to score 168 runs and lead Australia to victory. Who knows what happens? You can't really tell how he jumping so high. How he jumps so high. But when you drop a catch, it's much more damaging in cricket than baseball.
