I do think it has to do. That is the reason why I highlighted the "oder".
It tells that both terms, "die Welle" and "Axin ihres Vorticis Verticalis", describe the same or similar thing, the single common rotation point of the weights. As it is written, the external load is applied to that point and driven, and we know from the wheels drawings the external load is applied to the wheels rotation point/shaft, so the 2 must be the same.
Written in 2 sentences, we get
"an die Welle applicirte Lasten" + "oder" +
"an die Axin ihres Vorticis Verticalis applicirte Lasten".
From the front view drawings of Bessler wheels, we know that the load was applied to a horizontal shaft in the direction of z axis,
if we name the left-right direction as x axis, and the up-down direction y axis.
And not to forget, the sentence tells us, the load is applied to the "axin ihres Vorticis Verticalis" and not to
"vorticis verticalis". The "axin" stands naturally in an 90 degree right anlge to wheights rotation movement plane.
My conclusion, I think tornado movement is a very interesting phenomen and may not be excluded from possible principles for PMs,
but I don't read the sentence this way, it gives a clue to such a movement.
At last follows an impressive foto from the english
Wikipedia website, vertical rotation - horizontal axle.
