These terms feel right if an inversion of the overtone series is expected. But the
real pitches differ up to a major third.
As Guettler outlined above, the length of the vibrating string is not doubled.
The triggering is much more complex and the paths of triggering waves are
multiple.
With respect to the non-linear system of triggering ALF, further research
would probably lead to other factors, such as strange attractors or corpus
resonance.
In addition to the frequency analyses, I find it important to report on some
experimental series on ALF:
