It's very clear in the ARIN region as well. From=20 the ARIN Number Resource Policy Manual (NRPM), <https://www.arin.net/policy/nrpm.html#four11> -
"4.1. General Principles=20 4.1.1. Routability Provider independent (portable) addresses issued directly from ARIN or= other Regional Registries are not guaranteed to be globally routable."
Adding "or globally announced" may stop some of this in the future.
