The point is that (at the ISPs' request) the diffserv model allows
each ISP along the path to apply a different policy - so a packet
marked for EF treatment inside one ISP might be marked for AF
treatment inside another ISP. (You can argue that would be stupid, but
that's what the diffserv WG heard from the ISPs.) So different SPs will
interpret the same label differently.

Do they change the original lable, or just apply diffrent policies on the
same lable?

The Flow Label is unaffected. The Traffic Class field can be modified at
the ISP marking device.
