"very misleading article, the new Feinstein Amendment does NOT ban US citizen miltary detention"
...article paraphrases the quote your highlighted, but it basically makes the same point: The compromise was a clarification that the existing law stands.
ACLU
statementWASHINGTON - The Senate is poised to pass the National Defense Authorization Act, with an extraordinary expansion and statutory bolstering of authority for the military to pick up and imprison without charge or trial civilians, including American citizens, anywhere in the world. A last-minute amendment was negotiated between Sens. Dianne Feinstein (D-Calif.) and Carl Levin (D-Mich.) that passed, but does not prohibit its application to American citizens or others in the United States.
Additional amendments offered by Sens. Mark Udall (D-Colo.) and Feinstein to strike and limit the detention power were defeated despite strong showings of support.
The Secretary of Defense, the Director of National Intelligence, the Director of the FBI, the Director of the CIA and the head of the Justice Department's National Security Division have all said that the indefinite detention provisions in the NDAA are harmful and counterproductive to their work. The White House has issued a veto threat over the provisions.
"The bill is an historic threat to American citizens and others because it expands and makes permanent the authority of the president to order the military to imprison without charge or trial American citizens," said Christopher Anders, ACLU senior legislative counsel. "The final amendment to preserve current detention restrictions could turn out to be meaningless and Senators Levin and Graham made clear that they believe this power to use the military against American citizens will not be affected by the new language. This bill puts military detention authority on steroids and makes it permanent. If it becomes law, American citizens and others are at real risk of being locked away by the military without charge or trial.
"Given that the House version of the legislation is already very troubling, the final House-Senate negotiated bill will likely be even worse. Unless Congress somehow comes to its senses, President Obama should get his veto pen ready."
The Udall amendment and Feinstein's first amendment would have erased the ambiguity. The fact is that the existing law is being misinterpreted by some.

But Senator Mike Lee, Republican of Utah, said citizen terrorism suspects should retain their “fundamental civil liberties” in order to protect the founding principles of the United States.
“I think at a bare minimum, that means we will not allow U.S. military personnel to arrest and indefinitely detain U.S. citizens, regardless of what label we happen to apply to them,” he said.
Before voting to leave current law unchanged, the Senate rejected, 55 to 45, a proposal by Senator Dianne Feinstein, Democrat of California, to instead say that Americans are exempt from detention under the 2001 authorization to use military force.
The uncertainty over the current law added confusion. Some, like Mr. Graham and Mr. Levin, insisted that the Supreme Court had already approved holding Americans as enemy combatants, even people arrested inside the United States. Others, like Senators Feinstein and Richard J. Durbin, Democrat of Illinois, insisted that it had not done so.

Bottom line is that the reason these amendments are even needed is because of the insistence of some Senators to interpret the law in broader terms when they have no justification, legal or otherwise, to strip Americans of their “fundamental civil liberties.”
