Since graduation, I have observed a mismatch between the `total posts awaiting review` indicator in the upper right corner and the actual number of posts I see in the review queue when I click on the review button (or that indicator).

For example, this morning the indicator showed 7 posts needing review, but there were only 2 posts in the review queue. I reviewed both posts, and now the indicator shows that there are 4 posts awaiting review despite there being 0 posts in my queue. Sometimes I will review four or five posts, and the indicator will only decrease its value by 1. 

Is this a bug? Is this behavior the way it is supposed to behave? Is it showing me the total number of posts that need reviewed even though they all will not be allocated to me? If this last case is true, the indicator is misleading from the user experience standpoint. It is up there in bright orange telling me that there is work I can do for the site, which I want to do to.
