Yes, you're quite right! I didn't even notice this, and I don't think others did when testing the course.
I'll open an issue. It'll be an enhancement issue, so technically lower priority, but if many others like your post or are similarly confused, I'll bump up its priority.
update: one other reported in support (keeping still at low priority for now)
update #2: decided to not fix, as is clear in context, and otherwise used a bit ambiguously, maybe even interchangeably
