...he meant, don't use more than two allowances....on line 5 of the actual W-4 form.
putting a zero under total allowances (line 5) is OK, but may withhold more than you intend if you are submitting new W-4 forms to both employers.
IF you are doing this on only one of your W-4 forms, a zero is OK. IF you are submitting a new W-4 to both employers...perhaps a "1" on both (on line 5) will split the difference.
Remember that it will only be affect your withholding for for the remainder of the year. (And, you need to pay attention to your paystubs to ensure the change was implemented...when you submit...ask payroll/HR about which paycheck they think it will start)
When you file early next year, you can check out your refund situation and re-adjust at that time.
