I did that, even landed on the platform, but that's when I couldn't find anything else anymore that I could reach and didn't see any glowing wisps either. Eventually made my way to the base of the pillar at the far end, that has platforms surrounding it in a flower petal arrangement which seemed promising, but I didn't manage to go off into the other direction.
Watching the playthrough below shows me I should have tried to make my way to the top instead.
