Option 1 would result in a lot of reposts getting back to the front page and option 2 would be bothersome or redundant for users that frequent the new submissions page. I don't know how the current algorithm works but there has to be some exchange rate between independent submissions over a relatively short period of time (multiple days) to upvotes over a shorter period of time (multiple hours). I assume this is already part of the process and that your specific example falls outside of what the algorithm considers to be significant. EDIT: Clarification
