It is odd when a vendor offers such erroneous brewing directions, especially for a tea that is traditionally brewed cooler. Boiling water, 3-5 minutes, insane, who is writing this stuff.
My guess is it is low grade kabusecha which is kind of between sencha and gyokuro, production wise, but still likely low grade. Vendors will sell kabuse and gyokuro. It is wrong, but it happens a lot I bet.
You can try it at the really low temps we mention for gyokuro, but my guess is it won't come out right. I would also try sencha temps and times to see what happens.
Wow, those instructions are weird.
For one thing the instructions aren't gyokuro specific, it's saying them for all green teas. The second part is more disturbing.

The only thing that I can think of is that they live somewhere strange where atmospheric pressure is REALLY low? Normally I don't see water boil at 82C.# Bring the water to a rolling boil at 180oF (82oC).
