I don't think there is a scientifically rational explanation. I think it =
is a metaphor that someone has got from their teacher and has taken it =
as gospel. When used 'scientifically' it is b/s.

All one can control on the mouthpiece is pressure - how hard you blow. =
You can change the resistance inside your mouth, but then that just =
changes the pressure at the mouthpiece. That will result in different =
speeds of airflow through the recorder, which of course you indeed use =
differently for different registers. The temperature of the air may vary =
very slightly, but as you say it is not under your control. A fast =
airstream may feel a little cooler in your mouth since it may chill your =
mouth by evaporation of moisture, extracting latent heat (like a swamp =
cooler). Speed of airflow certainly has an effect on the recorder =
'whistle'.

On the clarinet, you can also change the opening of the reed by the =
pressure of your embouchure, and this will also affect the airspeed, but =
not on the recorder.

In my never-humble opinion, it is simpler and more accurate to say 'blow =
harder or less hard', but this sounds prosaic, and less as if it is =
received wisdom from A Great Teacher.

I am prepared to be argued out of this view but the arguments has better =
be good :). I loathe bad science.
