That procedure works if you are rotating the tires, then it will know the front from the back because of the different tire pressure settings.
But when I first installed snow tires on a spare set of rims I needed to perform the longer procedure that is as follows because of the new sensors;
1) Make sure all tires are inflated to the vehicle’s recommended inflation pressures (found in the owner’s manual on the door placard).
2) Turn the ignition switch to OFF then press and release the brake pedal.
3) Turn the ignition switch from OFF to RUN (engine OFF) 3 times, ending in the RUN position. Do this within 10 seconds.
4) Press and release the brake pedal.
5) Turn the ignition switch back to OFF.
6) Turn the ignition switch from OFF to RUN (engine OFF) 3 times, ending in the RUN position. Do this within 10 seconds.
7) The horn should sound letting you know the vehicle has entered into TPMS relearn mode.
? Place the top of the TPMS triggering tool against the sidewall of the driver’s side front tire in the location of the valve stem. Press the left button, wait until the horn sounds, then press the right button to turn the tool off.
9.) Once the horn sounds, move on to the passenger side front tire and repeat the process. Each tire should only take 30 seconds or less.
10) After the passenger side front tire has been learned, continue on to the passenger side rear tire and finishing with the driver’s side rear tire.
11) You may now turn the ignition to OFF. If the horn does not sound, the sensors were learned successfully. If the horn sounds twice, then the process must be repeated because there was a malfunction.
If you dont have the TPMS triggering tool people say you can trigger each wheel by letting air out but I just bought the tool, its like $30 or something.
I hope this helps
