While the idea of cross-grading was mostly developed in the context of going from i386 to amd64 (as well as a few similar upgrades in other architecture families), it is also useful when moving a Debian install from one machine to a machine of a different kind, e.g. from an amd64 machine to an arm64 machine. So the intention is not to take advantage of those hypothetical machines that can natively run both arm64 and amd64 binaries, but to let you move your system for example from an amd64 machine to an arm64 machine without needing a reinstall.
