Drag your clips into the session view and make sure quanitizisation is on and it behaves exactly like this. If it's set to bar it waits until the bar is finished before it will change over to another sample. Though it's entirely possible to create exceptions to this as well, each sample can be launched from one of several method and the timing of it can be messed with as much as you want.
