My speculation is as HOEPA loans are identified on the LAR, FRB can track numbers and dollar amounts in a variety of ways, including area concentrations due to geocoding info.
It can produce information as to the amount of HOEPA transactions being produced by regulated institutions, and be a determinate factor in deciding if any additional regulations are required.
Regulators will also be able to single out individual loans when conducting in house examinations.
