I would be very surprised if this technique is usable with any DBD driver. After all, when you have created a DBI connection, there is usually just one (and only one) database session available using the instantiated database handle with some driver specific resources allocated. Providing a universal method to clone such anything-structure seems next to impossible, but I'd be happy to be proven wrong.
Reading the posting you refer to, it also seems to be very experimental and some other posters had trouble with it.
Since you are not using transactions, why not just use two database connections?
