That's what I'm assuming. I'd imagine they figured it just didn't fit into the set, and despite the fact I'm one of these SDABTO-lovers, I really cannot see it exciting the crowd a whole lot.
It's a throwaway song. One of their few filler tracks. The only reason it made the album is because they didn't have any better material to put on it (remember that Zooropa was initially planned as an EP). I don't think it's a bad song, but I don't think very much of it either, and I don't think the band does either.
