well when he did a gig in Seoul last year, the setlist was almost same as current ones, except OFB and PUOTF. I have whole bootleg files of that gig and when he did OFB and PUOTF the vibe got a little bit depressed...honestely speaking, 'noticably' depressed... so I think he removed those songs after because of that..... just 'this is my interpretation' so dont take it too seriously...
