What each ingredient does

Red peppers
Supply the main pepper flavour and colour, which the hot vinegar draws out.
Strong vinegar
Acidic liquid that extracts flavour from the peppers and helps preserve the finished liquid.

The step that matters

Reduce to 1 quart. Boiling evaporates water and concentrates both the vinegar's sharpness and the peppers' flavour. Stopping at the stated volume sets the strength of the final liquid, so the reduction needs to be measured rather than judged by eye.
