Official source text from the 16 January 2026 Rules release
An ability that triggers at the beginning of a step or phase may trigger multiple times if it triggers at the beginning of “each player’s” or “each opponent’s” step or phase. These abilities trigger once for each appropriate player if the ability’s trigger condition, effect, or intervening “if” clause refers to “that player,” “that opponent,” or similar.
