How is that consistent with “transports the wearer to that branch” from your description?
Oh, I guess I was unclear. Time-turner does not delete a person from a timeline, this is expensive, unnecessary and violates General Relativity. A new copy of the wearer is inserted in the branched timeline where none was before.
In fact, this insertion is the only part of the time-turner’s description that is questionable under any known physical laws: It takes either energy momentum non-conservation or both FTL matter transmission and Lorentz invariance breaking to create something from nothing.
