1) Yes, it was to prove that it was indeed her sister.....and to try viewers of the trail of them being sisters "plot twist".

2) Zelena couldn't kill Emma for plot reasons. The second curse didn't depend on Emma being the savior, but I'm assuming that Zelena knew that if she fought Emma she would be defeated and likely killed. As we all know, Zelena didn't cast the Dark Curse, but they made it seem like she did. Unless she had other plans for Emma......
