In the basic execution model we talked about the pattern- and hold-space, but Sed has a third buffer the append queue. From the Sed script perspective, it is a write-only buffer that Sed will flush automatically at predefined moments of its execution broadly speaking before reading a new line from the input, or just before quitting.
