It is similar to having to pick reinforcements before you roll for map.
TI has the same wording as reinforcements so I would say that it is before you bring reinforcements (actually while you were doing it before reinforcements were revealed) is when you would choose (yammosk would be choosing at the same time as opp was choosing reinforcements) so the reinforcements wouldn't be there yet for the yammosk to choose.
There are not multiple steps to reinforcements. It is one action. And as with most things, you cannot interrupt an action unless it specifically says you can do so (djem so for example). Set up is a series of actions to a degree, but there is no designated breakdown of the individual acts within it. As it's written, TI happens at the same time as Reinforcements, not before, and not after, which means simultaneous effect rule enters into it.
And as always, the acting player is the person with it. I see no reason within the rules that would suggest the person with the Yam cannot take a Reinforcement CE if they choose to wait until after reinforcements are revealed to name it.
Again, the precedent for this I believe is the ending/beginning override and door resolution. You cannot interrupt the override resolution and even though it's multiple actions, it's considered one step. Choosing reinforcements is also one step - even though there are mutiple actions.
And once reinforcements are chosen, is it not still the set up time that the Yam requires? Of course it is, because you have not moved into a new step in the sequence, and you have not resolved TI. There is nothing the opposing player can do to force you to choose before revealing his/her reinforcements in my opinion.
