He absolutely was, quite famously. He'd be writing the episodes in the diner week-to-week.
For me it's the pattern for a lot of shows that went off the rails: starts with a strong premise and setting, but gets an indefinite run so the writer(s) can't actually terminate any story arcs and end up floundering badly. It got dramatically better again when he had to wrap it up.
Some shows start off in that state (like Lost - I was familiar enough with the pattern then to avoid getting sucked into that one); some drift into it (Twin Peaks and BSG at least). It usually takes getting cancelled to pull them out of it, which is really sad.
