Because the sealant repairs the hole with out losing much pressure 90% of the time...most times I haven't even known I had a puncture until I take the tyre off and find a blob of sealant patching a hole.
The other 10% of the time unless it is a huge cut it will still repair itself but you may need to stop and leave the hole at the bottom of the rotation so it gets maximum fluid into the area then repump.
All I can say is from 30 plus punctures in 2007 to 1 puncture (due to a big cut) in 18 months on tubeless...works for me.
