I got curious so I checked out the Raw and it's not the same prononciation (and I think not the same writting too).
First girl is written as "サーリン" (romaji: Saarin) which on Google, the writing can be either "Sirln" or "Cerlin" for example (strangely, I got some Star Wars references from Google), you can also think of it as "Sarline".
While second girl is written as "サリネ" (romaji: Sariné).
I think they should have come up a different name for the first girl since it's much more than a romaji writing compared to the second.
