It's a good phrase that really helped him in the last year or so. 434 days as champ suggest he is the best in the world. This, however, could result in a storyline. Maybe after all these losses he could have a small feud with Axel before returning to Brock. If he stopped calling himself the "best in the world" until he beat Brock or won a World Title it could actually lead to him becoming more interesting and giving his chase a slight edge.
