Perhaps the author is trying to include Schmitt triggers to sort of emulate mechanical escapements. I've occasionally used the things (Schmitt triggers) to help square up sinewaves, but never in a case where I was concerned about stability or jitter.
BTW, how do three inverters constitute a Schmitt trigger? Note: Wikipedia spells it 'Schmitt', 'not 'Schmidt'.
