Yes, needs clarification. The reason for it was to keep the float in the chain of command. Float has to leave regularly. About every hour to every couple hours. They shouldn't be at Site 2 for more than a half-hour for float.
Float is short term.
Use a pull for over half-hour. There have been changes on Site 3, so no longer need pull. Not sure, we don't even agree among ourselves. All should be under one supervisor. Could reassign Site 2 float to Site 3, and only be called in an emergency to go to Site 3.
