I don't know what a "backspring" phillips is, the backlayer phillips head is not the same as the front side attached phillips which satisfies the 8764 crosshead standard and can do JIS screws. It is a JIS driver, to be more accurate in label.
The back layer one is a standard phillips. *edit: apparently, the back layer Phillips has gone through 5 different variations and the latest version does satisfy 8764 and I guess is a phillips that can do JIS heads.
