Yes highest to lowest meaning sorted by relationship. You may not see that sort if you do not have the browser maximized. I know that is the case on chrome and think it is on firefox, that is the preferred browser for Ancestry.
You also can sort by date. The way yiou worded your comment makes me think you may not be seeing your lower confidence matches. you can move the relationship slider to the right to see more if you have not done that. I find most of my Shared Ancestry hints are in the two lowest confidence levels. that may not be true for everyone.
