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.
Wrt option 2, the new submissions page already contains stories that are currently on the front page, so it's already a bit redundant. Doesn't bother me that much.
