You need to read the latest patch notes for wvw.

World vs. World
General
Simple nameplates for enemies have been changed to triangles instead of circles, making it easier to distinguish between enemies and allies.
The Loyalty pip has been renamed to the Commitment pip. The Commitment pip is obtained by completing wood division the previous week.
1 up / 1 down matchmaking:
Starting this Friday at reset, WvW will begin doing 1 up / 1 down matchmaking. This means a single, third-placing world will move down one tier and a single, first-placing world will move up one tier. If there is a tie for last, no world moves down, which also means no world in the tier below can move up (as there’s no room). Similarly, if there is a tie for first, no world moves up, which prevents the next tier up’s last-place world from moving down. If there is a change in which worlds are being used for matchmaking purposes (such as when world links change), matchmaking falls back on the usual Glicko rating sort (plus a potential deviation-based shuffle). Even while 1 up / 1 down is active, Glicko data will continue to be updated as it has been when each week’s round ends. This way it is always current when it needs to be relied upon.
This is a new test to try to improve how quickly worlds can move into their proper place.
We can revert back to Glicko if it is determined that the new matchup style is more harmful than helpful.
Mmo players with a screw loose vs mmo players with two screws loose. All very important stuff.
