My guess is yes, that's what he meant.

Lazy lists in Lisp date from this paper, at least:
"Daniel P. Friedman and David S. Wise. "Cons should not evaluate its arguments,"
in S. Michaelson and R. Milner (eds.) Automata, Languages and Programming,
Edinburgh University Press (Edinburgh, 1976), 257--284."

This is probably pretty much the same paper:
"Friedman, Daniel P. (1976). Cons should not evaluate its arguments. ICALP."
