Play Top Tracks does not play from shown "Top Tracks"

I’m not sure how it’s supposed to work, but this is not intuitive. The section “Top Tracks” shows eight tracks. The link “Play Top Tracks” goes ahead and plays completely other tracks. It seems to queue about 20 tracks. Some of those might very well be the shown Top Tracks, but intuitively only the shown Top Tracks should be queued. What would the purpose be to show Top Tracks otherwise?
