I honestly don't even remember this sequence. ROTS mainly stood out to me, when i saw it, as the worst Star Wars film ever made (i have never even remotely understood why so many people love this one so much). Really, the only lightsaber duel that really stuck in my head at all from any of the prequels was Qui-Gon/Maul in phantom menace, and that's mostly because a double bladed lightsaber looks cool and the music was great. The fact that I've actually seen TPM more than once, due to randomly catching on tv once or twice, whereas I haven't seen the other two since they were in theaters may have something to do with it as well.
