You are only issued a boarding pass after any SecureFlight processing has been done and the name as shown on the boarding pass is not that as presented in the SecureFlight data. There is no requirement that the SecureFlight data match that in the name field and in most of the reservations I make it does not match and nobody's had any problems with it.

In other words, the TSO working TDC does not have access to SecureFlight data and can't do any matching to it. The only matching they can do is between the ID and the name field of the PNR, which has nothing to do with SecureFlight. So SecureFlight does not affect that process.
