Conduction Losses Calculation of SiC MOSFET

Good Day,

I have a question regarding conduction losses calculation of SiC MOSFET. So what i found in different research papers and in application notes is that you calculate the power dissipated during forward conduction, reverse conduction and body diode conduction of SiC MOSFET and if you add all three values you will get the total conduction losses of SiC MOSFET. This is something weird for me because previously when I was calculating losses for conventional silicon MOSFET, the losses in body diode during dead time was always accounted in switching losses not in conduction losses. Can anyone please explain why its so?
