If all five tires are rotated, the system has to learn the new sensor, and learn to disregard the old sensor. The sensor on the spare is not recognized.
So, after all five tires are rotated, you have to perform the sensor learning in the owner's manual, or if the dealer or the shop has the correct reed exciting tool, they can use that to learn the sensors to the BCM.
However, if you only rotate the four wheels on the ground, the system should not require relearn. This system does not recognize the corner the sensor is located; as in the system used on Vettes, Caddy's, etc. So, all the system looks for is four sensors with four unique electronic serial numbers (ID's). As long as those four ID's continue to send signals, the BCM is happy. Add in a new ID, and take out an ID with a five tire rotation, and the BCM needs to know the new ID is ok to recognize.
I have rotated the four tires on the ground twice, and replaced the two front tires once, and the system has never required recalibration.
