Comment 2 for bug 1471604

To test:
1) Have a site with two (or more) institutions
2) For each institution have setting 'Registration allowed' turned on
3) To make testing easier have each institution's 'terms & conditions' be set to different text. To do this go to Institutions -> static pages and select 'terms .. ' from dropdown - turn 'Use site default' off and then alter the text and save.

Once all that is set up - log out and click the 'Register' button.

You should be able to pick institution on register form and the choice you pick should populate some terms text below the form.
