[SmartCrawl Pro] SmartCrawl SEO Plugin: noindex pages and posts by default?

I noticed in SmartCrawl that the ‘index this post’ is disabled by default.
Am I right in assuming that, by installing SmartCrawl plugin without much attention, one might accidentally get his website no-indexed due to this default setting?
I’m happy I noticed it but I guess many won’t, resulting in the website losing SEO positions.
