Could be wrong, but believe Clorox "Ultimate" is nothing more than the type of bleach used in those stain pens also sold under the Clorox brand name.
Yes,surfactants can cause sudsing as they are "detergents". All bleaches work better with a little something to break down surface tension as they are better able to penetrate stains,soils and textiles. Normally there is enough detergent/soap in the wash cycle to provide this action.
Highly doubt Clorox put a new line into production just for "HE" bleach, and willing to bet it is nothing more than one of the many types already on the market, perhaps with a little twist.
