Rule 700.2d
Official source text from the 18 February 2022 Rules release
If a player is allowed to choose more than one mode for a modal spell or ability, that player normally can’t choose the same mode more than once. However, a few modal spells include the instruction “You may choose the same mode more than once.” If a particular mode is chosen multiple times, the spell is treated as if that mode appeared that many times in sequence. If that mode requires a target, the same player or object may be chosen as the target for each of those modes, or different targets may be chosen.
