I think so. I belive you're trying to read to much into this.

They say that a 1/2 wave dipole are considered to
have a 0dB gain. If you have a yagi with 10dB gain
then you are allowed to use max 5W pep from your
transmitter. They don't give a hoot about take-off
angles, hight over ground or anything else. It would
be to difficult for them to keep track off.

If you now have a 1/2 wave dipole at ground level, you could
raise it as high as you want, still using 50W pep, and it
would reach the other side of earth with multiple times more
signal strenght without violating the new rules. So, it is a
way to try and minimise RFI levels in a way that they can
control and verify, without neccessary actually keeping the
signal levels down if all people where to raise their antennas
to double their height above ground.
