The smaller diameter range non-reversible jaw set on self centring chucks still have steps on the outside for gripping the inside of cylindrical work, it's more common on smaller chucks that just one reversible set is supplied.

A quick and easy way to check is that the teeth which engage the scroll will have symmetrical inner and outer faces if the jaws are reversible,
