The name is quite misleading, something else might have been more appropriate.
But this behaviour hasn't changed (except minor improvements) since you
introduced it some years ago (see
https://github.com/dlang/dmd/commit/a1217f92f596bd9ce07f7c327a6980797085ba7d).

> make -f posix.mak AUTO_BOOTSTRAP=1

This compiles dmd using the fetched dmd installed to generated/host_dmd-2.088.0
as expected. Did some error occur on your end?

This doesn't work because the Makefile does not know about the "bootstrapped"
compiler and tries to use dmd found in $PATH. Might be worth to add some logic
to detect this.

> Why didn't AUTO_BOOTSTRAP leave behind a working installation?

Did you build druntime & phobos as well?
