Right, but what a lot of people don't realize is that what looks like "spam" is actually careful micro. In order to get the most effective unit control, it's actually necessary to order your units to hold position quite frequently while they're being positioned. It gives you some advantage, for example, if you just send your unit somewhere, it's possible for an enemy player to get close to your units and draw them to a disadvantageous place and kill them, where if you tell them to hold position this isn't possible. So what you are seeing that looks like spam is actually individually grouping large amounts of units and positioning and holding position at just the proper point.
