Interesting... I didn't. Just tested a few minutes ago actually.
I clicked the link, then searched, then went to Google.com and searched again and I was back to the new SERPs. I was also sent to the new results after clicking on the Mother's Day image at the top? Maybe try that and see if it clears the cookie or something? IDK... I'm using firefox and currently signed in to my account, but I did delete all cookies this AM and did not search again or login again prior to trying to old version link.
