Both macOS and Windows can translate existing legacy x86 code into native ARM64 code. This allows apps written for Intel Macs to run on Apple Silicon (using ...
As far as I know, current Windows on ARM ”cheats” by pretending memory order is not a problem.
Indeed, as your link confirms:
These settings change the number of memory barriers used to synchronize memory accesses between cores in apps during emulation. Fast is the default mode, but the strict and very strict options will increase the number of barriers. This slows down the app, but reduces the risk of app errors. The single-core option removes all barriers but forces all app threads to run on a single core.

Very good catch!
