The others are usually called "random turn-on", meaning that they turn on whenever the control signal is applied. If you want to control a load by phase control, like a light dimmer, then this is necessary. I think that is what the above Chinglish is trying to convey in your quote.
All SCR and Triac SSRs turn off at the current zero-crossing of the AC cycle.
