Will Google Continue to Index the Page with NoIndex Tag Upon Google +1 Button Impression or Click?

[globalsources.com]

The FAQs for Google +1 button suggests as follows:

"+1 is a public action, so you should add the button only to public, crawlable pages on your site. Once you add the button, Google may crawl or recrawl the page, and store the page title and other content, in response to a +1 button impression or click."

If my page has NoIndex tag, while at the same time inserted with Google +1 button on the page, will Google recognise the NoIndex Tag on the page (and will not index the page) despite the +1 button's impression or clicks send signals to Google spiders?

You could possibly have the +1 button point back to a page you want indexed like the homepage. So if someone clicks it, you still get the benefit but to a page you want in the index.

From http://www.seobook.com/smx-east-2011-recap-seobook:

"At this point it seems Google will crawl a page if +1 is present, regardless of the robots.txt. This could possibly create issues with trying to not crawl certain pages to avoid dup content. More information found here:http://www.webmasterworld.com/google/4358033.htm."

My guess is that they'll ignore your noindex tags too if you have a +1 button on your page.
