Can you have more than one nonce on a page?

This turned out to be a pretty straightforward bug with my own code.

The problem was my first form was checking for submission with a simple:

if ( 'POST' == $_SERVER['REQUEST_METHOD'] ) {

so it was being triggered even when the other form was submitted, and my wp_verify_nonce() check would fail and then it would call wp_nonce_ays.

To fix, I added this to the conditional:

and isset( $_POST['sidebar_form_wpnonce'] ) 

So yes, you can have more than one form/nonce per page.
