Errr, the theory I'm relating is that continuing the pressure of the antibiotic will make it easier for the body, and perhaps non-susceptible benign bacteria, to finish them off (perhaps not all, but to a de minimus number where they won't pose a problem). Remove that pressure, and the resistant population has a chance to rebound. More likely than having an ecology of other bacteria to fight with is that the field is somewhat or all but completely cleared. The body may not also have had a chance to clear up whatever condition allowed it to get a grip in the first place. Etc. Again, as I understand it TB is a great example to look at, and depending on where you live it might even be a real danger to your and yours, so maybe read up on it?
