example, we have our RIPE's IPv6 /42 prefix which is normally routed through surfnet bigger /32. But apparently some parties seem to strip the no-export community which causes the routes to be leaked.
which, because of the longest prefix match rule, resulted in quite "interesting" reachability paths for RIPE NCC IPv6 adresses in the past. TTM recorded cases where the /42 made packets originating in Europe first travel to the US (hurricane electric IIRC) before getting back to AMS. Not good for user experience ...

In this particular case, "Visibility" is "Leakage"
