I don't recall his reasoning but I'd bet it was due to the normal Thompsons having no setback and the "bent" Thompsons with setback have a minimum required extension so the "bend" stays above the seat tube.
There are no other mechanical objections Ii can even imagine and the Thompson's are relatively high priced but no where near what some others charge.
