Codes are not meant to be ran together, but if someone did...
1. If you activate/deactivate before race results, the Change Miis code would take priority as it executes later at a ScorePage function (very moment results appear). You would swap to next legit Mii in your Database regardless of what your current Mii is.
2. If you activate/deactivate at race results or at next-race/continue screen, this code would take priority.
No matter how many times the Change Mii code has cycled Miis, you can always deactivate to go to your legit Mii (as long as point 2 is followed).
But this is all in theory and at quick glance. Chances are, something will botch, and desync or even a freeze will occur.
