No, not about graphic flags. This thread is talking about country flag / planet flag / fleet flag / etc.
In 1.5 flags can be set as <name>@<target>, where <target> can be any scope, such as this, fromfrom, prevprevprev, owner, solar_system, root.species, or even event_target:<target_name> . The game will automatically translate target scope.
For example, if there are two planets owned by different countries each has planet flag test_flag@owner set, the two flags are different. In a country event, random_planet = { limit = { has_planet_flag = test_flag@root } <effect> } will correctly execute effect for planet with previous flag of that country only.
