Obama administration "pushes out cash" before Supreme Court strikes down Obamacare

Is this right?  If Obamacare is struck down, this money on setting up state exchanges will be a complete waste.  From Politico:

But the administration has forged ahead, spending at least $2.7 billion since oral arguments in the case ended on March 28. That’s more than double the amount that was handed out in the three-month period leading up to the arguments, according to a POLITICO review of funding announcements from the Department of Health and Human Services. . . .Six states — including three states that are part of the challenge to the health care law — benefited from $181 million in grants announced in mid-May to help them set up health exchanges. The exchanges are new, state-based health insurance marketplaces that will go into effect in 2014 if the law is upheld.And earlier this month, another four states — including three that are opposing the law —split $295.6 million in enhanced Medicaid funding provided by the law to encourage states to provide long-term care to patients in their homes. . . .
