That's the only way I can explain my good "luck" on wider (38-42mm), low-pressure tires that have no special flat protection whatsoever. It seems like there are more and more patches of broken glass between my house and work (or the local watering holes), and I don't always see them before I hear that sickening "kssht-kshht" sound.
But it might as well be sand for the way it sticks for another revolution or two, then gets brushed off again.
I also suspect -- without evidence to back it up
-- that this is part of why "road tubeless" users happily report fewer flats. Yes, sealant does a great job of plugging holes in the casing, but roadies have also moved up from 23mm tires to 25, 28, even 32mm in a lot of cases, and dropped their tire pressures accordingly.
