In the topic I referred to earlier:
The taxon Heartleaf Foamflower (Tiarella cordifolia) got split in two with a new taxon called Creeping Foamflower (Tiarella stolonifera), called as such because of the root structure. Unfortunately, the split covered a large geographic range, so pre-split people who called it Heartleaf Foamflower in the affected areas would technically have to call it Creeping Foamflower to follow the split. @tiwane’s comment near the end of the topic sums up the iNat stance on situations like these.
