Rule 122.8
Official source text from the 7 August 2020 Rules release
If a triggered ability instructs a player to “put those counters” or to “put [an object’s] counters” on another object and that ability’s trigger condition or effect checks that the object with those counters left the battlefield, that player puts a number of counters on the second object of each kind the first object had before it left the battlefield. The player doesn’t move counters from one object to another.
