Have you looked at the latest version of the sample code (for the 3.1 release)?
It has several improvements to make it simpler to use Google and Yahoo authentication together (with different attribute exchange configurations simultaneously), uses a similar login dialog to stack overflow and performs simple registration in the case of users who have not previously accessed the app.
See this issue https://jira.springsource.org/browse/SEC-1431 (and the linked one) for more information.
