No. The author just seems to be rather excited over having found a random factoid that few Americans know about.
The Germans were surprised by two major logistics problems in 1941. The insane amount of prisoners, 3 million over a few weeks, and early autumn rains turning the Russian roads and fields into mud. The latter crippled the strategic and tactical mobility of the Germans and stopped their advance. The Germans were not prepared for a long war, didn't have winter equipment for an entire army, much less for several of them. That's where the eastern front turned nasty for the soldiers.
The western front definitely had the lower priority. The Allies didn't send tank armies that span the entire horizon. During the war against Russia, the Axis forces lost 10 million men on the eastern front, 800k on the western front.
Stupid. NAZIs could have and would have made new axles that fit Russian tracks if it were a big issue deal maker or breaker. I guess you imagine otherwise? Like the Germans couldn't fabricate axles that size? And that's why they lost WW2? The explosives raining down from the sky and the entirety of the Western World shooting bullets at their soldiers had nothing to do with it? Or just a side-issue?
