That's not true.  autoreconf.in:autoreconf_current_directory
greps for /^ACLOCAL_[A-Z_]*FLAGS\s*=\s*(.*)/
so it really only works with autoreconf to put literal stuff in that
line.

When aclocal is run from make, as triggered by the automake-generated
rule, $(ACLOCAL_AMFLAGS) undergoes usual make expansion of course.
