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.
Mostly they only had a limited window to sac Moscow before Russia could muster all of their resources to stop the nazis. Originally it was predicted aftert the initial invasion of the nazis into russia that Moscow would fall in about a month, but supply lines and holdups in areas like stalingrad delayed them too long so they couldn't take out the Soviet hq before reinforcements arrived
I'm not a student of that chapter of history, but the picture I got was that nobody was prepared for how incredibly cold Russian winter actually was.
edit: and that same story played out several times in modern history, as I understand it. Don't send yer guys to the Russian front in windbreakers and t-shirts. The only people who successfully kicked Russian ass in that cold fucking weather were the Finns, not a warmongering culture, but they can definitely do what needs to be done in chest-high show at 20 below zero, because they're used to it.
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?
