I am not completely sure, so don't quote me on this, but I am pretty sure it matches them depending on Level (Ex. Level 75 vs Level 70-75), and Rank (Ex. Rank 54 matching up with rank 45), and declare time (Ex. All Rainbow Alliance guilds declare in big mass to make sure we get an ally and can do strips.)
