I think it was the later migrations that got pushed into China - one example given that I remember was the Magyars, which makes sense. A lot of these tribes headed west because of a weakened Europe - here they head east because of a weakened China
We don't get a whole heck of a lot of details about Eurasia from what I recall, but I believe there was something about Iranian or possibly Tocharian nomads taking over China that I was a bit skeptical about.
I have the book! One implausibility is that ITTL Alexander lives until 280 BCE... and dies at 76. That seems highly unlikely for a person with his lifestyle in this time period. I'm not saying he couldn't have lived longer, but 76 years old? Come on...
His successor Alexander II is reported to rule over an empire that stretches "from Iberia to the Ganges River". This empire enters decline around the turn of the millenium and by 300 CE "the last pretence of political unity was gone". There's a lot about the Iranian-speaking and Tocharian groups migrating into China, but nothing about Germanic peoples.
Overall, I say it's pretty realistic.
The North American stuff seemed fairly plausible, what with the Aztec hegemony collapsing and a bunch of independent Nahua speaking city states replacing them, I also seem to remember reading something somewhere saying that Mexico was on the cusp of leaping into the Bronze age like the books mention happening

Inclined to agree. It's not half as wild as The Peshawar Lancers.
