Last month I answered a question on MO, which was later migrated to MSE. Upon migration, the up/down votes for my answer were migrated from MO to MSE. That makes sense. What I find strange is that the pre-migration up/down votes for the question are now counted twice, in the question asker's MO and MSE accounts. Is this intentional and/or desirable?
The question is Branch points lie in P^1(Q-bar), asked April 5 on MO and migrated April 9 to MSE. It received an up and a down vote on April 5, and reputation for those votes currently appears in the asker's MO account and MSE account (under the April 5 tab). In addition, the question itself is still listed in the asker's MO account. By contrast, the reputation earned from the April 5 votes for my answer was eliminated from my MO account (and moved to my MSE account) when the question was migrated to MSE on April 9, and the answer is not listed in my MO account.
