I thought the same but I changed my mind when I saw Esaul there, he doesn't specify what version of Esaul but the one that hasn't been released is from 2000, not Xero era. If I'm not wrong Explode is the title fans gave to the demo of Part Of Me (but I'm not so sure, I found this name on a YouTube video). Plus I don't understand why Fuse has been put in the Hybrid Theory era seen it's from 1997.
