Any idea why some people think it does? Maybe they are thinkingthe engine is being stopped...

I've also pushed it back into drive while still coasting occasionally, and it doesn't seem to do anything bad, but I hesitate to do it regularly.
I also drop it back into drive whilst moving, seems smooth to me even at 50-60MPH
