I've just drew up a quick little stick figured pic of this close up problem..
The 2 lines coming out of each of their heads are their Shooting Cone Deviation..
As you can see they can clearly see each other...
but the red dot is their origin.. and that is what is used to check if he is aiming at the other bot or not..
and you can see in the pic.. the dot is not in their shooting cone deviation..
so right now they think they are not looking at each other..
their aiming will never make them look at each other's origin because these are skill 100 bots which aim for head..
