When running /give @p player_head[profile=<name>] or letting it be run by a command block/datapack, each time the command is executed a subsequent inventory slot is filled even if the name stays the same.
This does not happen if the profile component is not used and also doesn't happen with other components like custom_name.

Can confirm. This happens because when the item is initially given by the command, its
profilecomponent has different tags than the other player heads already in the player's inventory, because the component is altered by the game afterwards.
