This is not entirely true. It works in your case because of the other deductions to reduce your overall tax... but for those who will end up owing large amounts using this method, the government will also add on an "underpayment penalty". The general rule is that an "underpayment penalty" is usually waived when the taxpayer owes less than $1000 or the taxpayer has paid (via withholding and/or estimated payments) 90% of the total taxes due.

As with most tax situations, YMMV, but offering generic statements/advice like the one quoted above, it not a good idea... especially for one who is not a "tax professional".
