Possibly because the On/Off/On state is faster than 10Hz? In other words, at 20m/min your axis is moving 333.333mm/second so 1/10 of a second it moves 33.333mm so if your screw hole is less than 33mm dia (very likely) then there is a good chance the brain will miss it.

So the switch must be ON for more than 0.1s and OFF for more than 0.1s to make the count?

The brain has to see it, if the brain works at Machs update (10Hz)  then your on/off/on state is likely much shorter than 1/10th of a second so there is a good chance the brain will not see it.
