This is an application of the infinitesimal criterion, as is shown in the proof given in the reference you mention (where the expression "without any further assumptions" in their formulation of Prop. 5 of section 7.6 does not entail the etaleness from the preceding line in the text, as you can see when reading the proof). | |
