The article states:
"The FBI official pointed me towards this Bitcoin address, which according to the public Bitcoin transaction record known as the “blockchain” received transfers of close to 144,000 in just the last 24 hours. “They finished moving them at 3am this morning,” said the official."
So no, they have already "spent" them by transferring them to another address. If they've already been spent then Bitcoin shouldn''t allow them to spent again from a "backup", otherwise it'd be worthless as a currency, you buy X from me with the coins, I send you X, then you can spend them again rom this backup depriving me of the value.
