-Notice, however, how some competitions do not have this provision at all: the FIFA World Cup is one prime example, where head-to-head criteria apply after the overall one but there is no requirement to restart them at any point should they only help to separate some teams, but not others. This behavior can be replicated via the third and last accepted value, `"none"`.
