That is boiler plate text for Strat single coils and may appear on many Strat pickup pages, unfortunately. If you go to the Duckbucker page directly, it's not there. There is a tooltip on the position selection however which has a disclaimer right at the beginning that says not all options appear on all pickups.
"STRAT POSITION INFO (not all of these are available on every product family):- Neck/Middle/Bridge position models will have the same output, wind direction and magnetic polarity.- Middle RwRP position (reverse wind/reverse polarity) – choose this to have a pickup that will be hum-cancelling with one of our neck or bridge models. - All sets, except the Jimi Hendrix signature model, come with a Middle RWRP as the Middle Pickup.- Left- for some models with vintage staggered pole pieces, we offer a left-handed option. The stagger will be reversed for left-handed players.- Tapped- High output models may have a “tap” option available. An additional lead wire is placed midway through the coil wind, allowing wiring to a push-pull pot or mini-toggle switch to give an additional vintage output level option."
