Ah! I am starting to understand. Leap Second steering is accomplished with the PTFF instruction and is independent of CVTLSO. PTFF appears to slow down the physical clock.
So ... steering and CVTLSO are essentially alternatives, right? CVTLSO should not include any leap seconds that were previously (or were about to be) "steered" -- is that right? And if a shop is using STP it is probably not modifying CVTLSO: CVTLSO is probably either zero, or at least stable. Am I getting this right?
