Roth IRA back door contribution while having more than one traditional IRA account

Looking for guidance on a back door roth contribution from one traditional IRA account while holding another/second traditional IRA account with a balance. 

If you have a second traditional IRA acount with a balance and do a back door roth contribution conversion from another traditional IRA account which ends up at $0 after the back door roth conversion, and later in the same tax year fully convert that second traditional IRA that had a balance to the roth IRA, will you still  end up paying double tax on the attempted back door roth contribution conversion?
