Compounded and recalculating are different. Compounding specifically is adding interest to the principal balance, like a credit card.
I pay over my mortgage payment every month, so my principal is reduced at a greater rate than the original amortization schedule predicted. At the end of the year, on my yearly statement, it shows the "new" amortization schedule for the upcoming year based on the rate recalced to the new outstanding principal balance.

If it was truly compounded, semi-annually, then every six months your outstanding principal balance would jump by X amount, which it doesn't. It's always a decreasing amount.
