Annoying Zune Flaw

According to this page, it is possible to view pictures while listening to music, and then press the back button and return to the Now Playing screen. However, this isn't what happens.

1. Navigate to and play a music track, or start a playlist on your Zune (you know, those 4 other people in the world that actually have them :-p ).
2. Hold the back button for a few seconds to return to the main screen, or press it repeatedly until you return there.
3. At this point, if you press the back button again, you will return to the Now Playing screen.
4. However, if you instead navigate to and view a picture, you will no longer be able to get back to the Now Playing screen by pressing the back button. If you follow the instructions in the page linked to above, you will return first to the main screen, and then back to the image you were just viewing.
   
5. If you really want to return to the Now Playing screen, the only way I have found to make it work is to navigate to the main screen and then wait about 10 seconds. At that point, the UI will switch to the Now Playing screen.
6. What's interesting is that at this point, if you now follow the instructions without first viewing a picture, it works, and you will return to the Now Playing screen.

What gives? Is this how it "should" work? It seems inconsistent, and, the first time it happened, it was very annoying, because I didn't know how to get back to the Now Playing screen. Honestly, I think they should fix this by just having a "Now Playing" (or "now playing" ;-) ) option on the main screen.
