When you select one of the Activities, a little message pops up saying something like "keep the remote pointed at your system". It then proceeds to cycle through each device and issue the appropriate commands. I haven't noticed any problems with commands failing to register with different components, all devices have always turned on/off or responded to the button I pressed the first time. And I am just keeping it generally pointed in the direction of my setup, not at any specific portion of it.
Strangely, it seems like it spaces out the commands a little bit, so overall it takes a little more time to get everything started than I used to when I was controlling multiple remotes myself. But that's a small price to pay for the simplicity.
I have had problems with my old remotes that you really had to point them at the right place when the batteries are low. But with fresh batteries I've found you can bounce the signal off the ceiling or rear wall and the components still pick it up.
