No, it's not.

MPX means multi-pointer with multiple focus points. That means that two mice, 
for example, control two different mouse pointers on the screen.

Multitouch means there are multiple touch points, but they all come from one 
device. You can conceive, for example, that a touchscreen could detect the 
hands of two different users and report as two different pointers. That way, two 
people could work on the same touchscreen and handle different applications, 
each user having up to ten touch points.
