What is the actual purpose of the buffer retainer pin?

Part of the cycling or just to keep the spring in when breaking rifle down?

Actually it keeps the spring and buffer confined to the extension tube all the time. Not just at breakdown. The bolt carrier travels to the buffer and spring, never the other way around.
