The vote might have been reported if they registered on the same day, but possibly not their party status, so I think more research is necessary.
However, one of the reasons Dem states like same-day registration is that it gives no time to verify the voter. This person may have already been registered (perhaps under a slightly different name or under Mickey Mouse) or be using a vacant lot as an address, etc. Same-day registration is essentially a set-up for election fraud.
