Either or works... but I like to do it just before the corner so that I can pull through with ease.

"Do it ONCE, do it RIGHT!"
Fuel on most imports these days, and many days ago, is cut under decelleration. Gas mileage should not be worse... some of my best gas mileage I ever got (50+mpg) was in the mountains from a combination of this and other benefits
I've seen some newer stockish Hondas get driven hard at the track, decel from 7500rpm and after several years of abuse, starts to let by some smoke. Likely combination of rings from some lightweight parts succumbing to too much heat at high rpm, and valve seals. My friends Swift Gti was bagged with 300,000kms and 7 years of constant auto-xing, nitrous, etc. bouncing off the revlimiter at 7500rpm vs. in some corners where it wasn't a bonus to shift, rev-match to high rpm decel on the street (at least everytime I was in his car), and the car never blew smoke.
That said, perhaps the ol carbed V8s would have a noticeable effect in daily efforts to slow yourself down, but you are not likely to really notice the wear and tear from normal driving on the street. Properly designed exhaust brakes (not Jake brakes) on diesels would be globally frowned upon if they were known to 'accelerate engine wear' to such noticeable levers. There are many worse life shortening situations for a car to be in.
