What could be the reason that Obama sometimes says mandated health insurance is a tax and sometimes he says it?

is not a tax? He initially stated mandated insurance is not a tax but now states (in response to lawsuits) that it is a tax.
--------------------
It depends who he is talking to. If he is trying to convince the electorate that he isn't breaking is no new taxes on the Middle Class then he claims it isn't a tax. When he is trying to convince a judge that it is Constitutional then it is a tax. He is the most openly dishonest President we have ever had..
