How do you know? Might you be getting this from Hofstadter, who might not be representative? I believe that Winograd understood the limits of the approach and considered it a dead end, perhaps even a failure. Certainly, his failure to follow up suggests pessimism.
In 1973, Winograd moved to Stanford University and developed an AI-based framework for understanding natural language which was to give rise to a series of books. But only the first volume (Syntax) was ever published. “What I came to realize is that the success of the communication depends on the real intelligence on the part of the listener, and that there are many other ways of communicating with a computer that can be more effective, given that it doesn’t have the intelligence.”[4]
His approach shifted away from classical Artificial Intelligence after encountering the critique of cognitivism by Hubert Dreyfus and meeting with the Chilean philosopher Fernando Flores. They published a critical appraisal from a perspective based in phenomenology as Understanding Computers and Cognition: a new foundation for design in 1987. In the latter part of the 1980s, Winograd worked with Flores on an early form of groupware. Their approach was based on conversation-for-action analysis.
It that’s correct (and I see no real reason to doubt it), Winograd shifted his views a few years after SHRDLU, and after encountering dreyfus’s arguments.

Hey, wikipedia says that, so it must be true!
But also from wikipedia:
