You amazingly did not read my post - your focus is on the second event - it's only a second event if you have a serious first event - in this case it was borderline nonexistent or mild. They took a very conservative approach - which is fine but let's not get carried away with hyperbole.
And amazingly, you did not either... You are wrong on the second impact invent only being relevant if the first is a "high grade" concussion. Read what I posted. But since you won't because you live in a delusional universe, I'll post it again -->
...even the mildest grade of concussion can lead to SIS. (Clinics in Sports Medicine via Wikipedia)
So to sum, if Vital's concussion was only "mild" as you insinuated it might be, he is at risk for SIS which in real terms put's him at risk for a catastrophic head injury. No, we do not have evidence of that happening in basketball. But the risk IS there. An elbow, blind screen, etc. all could have life altering effects. But to you the risk is worth it.
If this is part of the shtick then it is just too far. If this is real, then I'm legitimately disturbed by how obtuse you are.
