I'm glad that worked out for you. Could'a been a bad day.
With a blowout, a TPMS may not register any alarms prior, but it would have certainly sent an alarm, or you would have noticed a sensor drop off, as soon as it occurred instead of relying on a courteous passerby to let you know.
Part of having a TPMS is not just waiting for it to send an alarm. It helps to predict a potential tire failure if your regularly monitor tire readings. Many times you'll notice one tire or other acting not quite like the others that can alert you to a potential problem.
I don't feel it is necessary to replace a tire after a slow leak repair, but "If in doubt.. change it out".
