In shomen uchi ikkayo Tori should not wait for uke to make shomen. Rather than wait for uke to strike, Tori initiates the atemi [both to Ukes face and body ]then if Uke defends against this attack from Tori [by Ukes instinctive action of defending his /her face ] Tori cuts through strongly , taking ukes posture.This is irimi -entering into Ukes centre .Imo this is a case of Tori initiating both an attack
and finishing uke off with an aikido technique.A case of pro active action by Tori. Cheers, Joe.
Sounds like standard Iwama and some old school styles
