The subsequent mov ebx, 9000h will cause ebx to "point to" a new underlying register, leaving the one that corresponds to eax intact.

  So every time a new value is loaded into one of the "high level" registers, it's actually loaded into a new underlying register? So the underlying registers are basically immutable?

    Yes, it's a allocation technique called "single static assignment".
