Would think this to be highly unlikely as this was introduced a period of time after they discontinued the original purple coloured super plus, thus they must have realised there was still a market for them to in effect re-release them, with a different colour. That seems to be the thing for quite a few manufacturers, to have a popular plastic backed nappy before making them cloth backed. Sales fall off and then they release a new plastic backed nappy.
A few examples that spring to mind. Molicare obviously, Tena with the active fit and I think iD slip went all cloth backed before bringing plastic backed back out. Although not a brand that I use but also Depends.
