No, it does not apply. THat is a BJT transistor. The two types of BJTs are NPN and PNP. The two types of MOSFETs are NMOS and PMOS. Saturation is unfortunately used for both devices but they are referring to completely different things.
[EDIT:] I think I may be mistaken. Although saturation means different operating modes for both types of transistors, they both happen to be the most efficient when being used as a digital switch.

I kind of forget how BJTs work so...yeah...read what I write critically.
