The part that you quoted was from the hypothetical drilling that they were planning before they started. When they got down to the depths they were expecting supercritical brine aquifer chambers (5-6 miles), they drilled directly in magma. They found their drilling into the magma allowed water from natural fracture layers to seep down and create a superheated steam chamber. They were able to put in a stainless steel collar to this chamber and that is where it is now.
This is nothing like PGV. PGV uses the now becoming outdated method of finding deep, natural pockets of superhot brine aquifers about 2 miles deep, not anywhere near the depths they are drilling in Iceland. This is more difficult because low resolution acoustics are being using to locate these pockets of brine aquifers since they want to drill into those rather than magma. There is a new paradigm for geothermal power coming.
