Maybe its the same loose definition, in the way that some of the tracks on TPOE were 'left over' from the Nation 12 sessions, and Sideways/From Trash and The Garden/Systems etc etc
The ideas/songs were conceived at the time of the previous album (or even earlier), but felt not to 'fit' when it came to final track selection.
They were then completely re-worked next time round and sound nothing like they first did.
Thus "Like A Miracle" was 'left over' from Metamatic.
John Foxx has always recorded more tracks for an album than actually get used, so to have some 'left over' is nothing new. Its just the wrong term - makes the tracks sound second best somehow...?
