I don't know if they got the explanation mixed up, but here it is...
"Class 3 to Class 3 radios is 10 Meters; Class 2 to Class 2 is
about 30 Meters and Class 1 to Class 1 is anywhere from 50 Meters to
100 Meters (the Bluetooth spec says a Class 1 radio is simply any radio
that has at least 7dBm and they go all the way to 20dBm so it really
just depends on the output power to what range they can achieve.) Now
that is standard out of the box specifications, but you can also get
weird combinations like Class 3 to Class 1 and get around 30 meters or
so. There are also a lot of differences with different types of
antennas, so if you put special antennas then you can get further (we
achieved 60-80 meters between two class 3 radios with two high power
antennas.) You will also notice different range in direct line of sight
verses through interference. Finally, light and other devices can
sometimes cause slow down like a very high power color laserjet printer,
for example. <<it's all about physics>>"
