Well this is a hypothesis to be sure, and it may be a valid one. I am
not qualified to say if that is the case. But I'm also not sure that
there are no other reasons for the phenomenon. And in any case, it is a
cylindrical instrument closed at one end overblowing an octave, the
natural consequences of which were earlier and emphatically stated to be
exactly the opposite. So such a rapid dismissal of what appears to be a
violation of previously stated principles seems to be hasty.
