Not silly at all.
Since it is a cheap and basically "non audiophile" amplifier chip, it is biased AB, at relativley low quiescent current. It would not be possible to put a complete class A amplifier desgin at that power rating on a single chip, since it would be impossibe to get the power dissipation managed.
