I was waiting for some seniors to chime in about this, but I will throw my 2 cents out there. I have dabbled in Uechi Ryu for 30 years under a couple of instructors and do not recall any of them ever saying anything about doing Sanchin no more than three times a day. When I get the chance I will ask Dave (my second teacher) if his first teacher said anything about that, because I do know that teacher was very formal on Sanchin always being done in the same pattern with the same number of steps, and was always done very 'hard,' something Dave had modified due to other influences by the time I started with him. My first teacher on the other hand did not always do Sanchin the same way every time, for example he would often have the entire class doing Sanchin from one end of the room to another before turning regardless of how many steps were involved, while he would move around among the class correcting and checking the students, and I think we did it more than three times some classes but I cannot recall for certain.
As for why some teachers may have a rule about doing it no more than three times, it could be from a notion of not overdoing a strenuous activity, but I suspect it has more to do with "three" being in the name of the kata and the related importance placed on the number three in some Asian cultures.
Again, just my 2 cents.
