I have this tracked down. You cannot have any more than one code in the "waiting" state.

Steps to reproduce:

1. Have WP send to first user. Do not enter the code they received yet.
2. Have WP send to second user. Do not enter the code they received yet.
3. Try to enter text message code for first or second user and neither work.

I hope that helps.
