While I'm not sure about any specific record, the reason they'd use different styluses is probably because they don't know which particular style was used to cut the original media. The closer you are, the better the reproduction should be. Too narrow a needle and you'll wobble in the groove too much. Too wide and you'll end up ignoring higher frequencies and loose content. I'd also imagine the state of the media to be relevant, i.e. scratches and other defects will be picked up differently on each size of needle so you could even piece together a composite of each needle if one picked up a scratch and the others didn't.
