You almost had the spoiler tags right. Just drop the 's' from the end of the word inside the brackets and you've got it. Like this: [spoiler]. Regardless, as you said there were Spoilers in the title of the thread, and players should know not to come in here, the tags aren't entirely necessary.
To answer the question, there's actually a trait in the Player's Guide called "Accidental Clone" where one of the PCs went through a similar trap and, well, ended up as Sorshen. I think Sorshen's reaction would likely include amusement. After all, she's been awake for some time, observing and gathering information about the world. She's likely already aware that it happened. She may have some curiosity - for instance, how is it that someone else's soul came to be in her clone body - but otherwise I don't think she'd be too put out by it.
In the second book, Sorshen uses scrying on the party, and if a player has the Accidental Clone trait, it imposes a -20 on the Will save to resist it due to Sorshen's familiarity with the subject. I imagine similar would occur if she ever met a PC form Shattered Star who'd been through the same trap.
