I am skeptical of that explanation.
Pressure when depressing the levers are as high, if not higher than anyone could ever exert when pushing the pistons back.
Maybe there is something I don't know about Shimano levers that explains it and I'd be interested to hear.
Either way, please proceed with caution and test really hard braking under controlled conditions before you descend down the side of a mountain.
