I poked around a bit, and I think they have to actually sign in with the new account before its in the table, which makes sense, and means the #s are reasonable.
This is certainly my understanding - the account is created as-and-when you log in at the new wiki, or visit it whilst remaining logged in.
(This latter part, especially with people looking at article interwikis, will probably account for quite an upsurge in account creation post-SUL...)
