The note under each episode is why that episode named it. They differ, and the difference is worth keeping.
A link here points at the source. It is not an endorsement of everything in it, and it is not a claim that the episode represented it correctly. Where a citation turns out to be wrong it gets a dated correction on the episode rather than a silent edit.
