Jake,
Your timing on this question is amazing.
They just published my article on How to Set Up Multi-User Administration on Pogoplug Biz.
If you see that article you will see it shows how it is supposed to work and did for me when I wrote it.
But after reading your post I tried again and received the same thing as you did.
The email that was sent out to the new user showed his email in the body of the text instead of my email address. In my original post the email shown was from me.
I will contact support and see what may have changed.

A bit more background. On this URL:
http://support.pogoplug.com/entries/256428-users-settings
The author says:
"To add a user, click the "Add User" button. Enter their email address and click OK. They will receive an email from Pogoplug asking them to create a password for their account."
This is NOT true. There is no "ask to create a password" on the page. It's just a login page (with a forgot password option) and an option to activate a new pogoplug altogether. No "create password"
Here's the screenshot of what I get when I click through from the account creation email:
