I think you are right
When I visited India this past early April, I thought my case would get approved while I was back home (being an optimistic person I am). To clarify, I talked with my lawyer and he said something similar to what you mentioned in your posting.
Hope this consolidates your opinion, but please do consult your lawyer before you travel outside the country with a pending 485 application thats too close to being approved.
