I suspect the issue with coasting/towing a Honda in neutral has to do with lubrication. Extended periods likely run it dry. But I suspect under EOC conditions, the lubrication is probably getting replenished often enough to mitigate damage. But that's just a guess.
However, I agree that if it's an automatic you shouldn't power off. You can ruin a good Honda tranny that way when done repeatedly. You might try switching to a manual tranny (this isn't too terribly hard or a mechanic can do it) instead.
Hot-tempered replies aside, the underlying idea is correct - hypermiling with EOC in most automatic tranny vehicles is not usually wise IMO. YMMV.
