I've found that this isn't always the case.
From the Integra shop manual:
"During deceleration with the throttle valve closed, current to the fuel injectors is cut off to improve fuel economy at speeds over following rpm..."
Basically standard engines are 950 rpm U.S. and 1050 rpm Canada.
...but I don't get the 9999 mpg indicator (and never have in tons of rental cars). So anyway, I often downshift on exit ramps or up to lights if I have to stop unexpectedly.
You can generally see and feel the transmission/TC give a bump in revs right below the cutoff.
Modern fuel injection probably has it -- at least OBD-II, maybe earlier...
