Has this ever happened in MMA?

Specifically the lead hand block of the rear hand/parry.

Is there any practicality for this technique in real fights?

I have seen more examples of the rear countering the lead in mirror stance than the other way around.

I wasn't referring to the hulk up. I was referring to the lead hand block of the rear/parry.
