My reading is the same: if after expanding an alias the path does
not start with "/", the search starts at the current package,
otherwise it starts at the root node; and no further alias expansion
is done.

It's a corner case for sure, but at least the standard doesn't
require us to implement recursive alias expansion; let's see if
common practice does ;-)
