That's actually not true, you are referring to a very bad "cooking" that Samaras presented to Merkel at the fall of '14 which was proved to be too stupid to talk about ever again...
Actually that is true. He was referring to Greece having a budget surplus, not a plan. They missed their target surplus but still had a budget surplus for 2014 of near 2 billion euros.
The current finance minister says they cooked the books: yanisvaroufakis.eu/2014/04/24/greek-statistics-are-back-primary-deficit-presented-as-surplus-with-eurostats-seal-of-approval/
Your link is about a 2013 budget surplus and not 2014. The reason eurostat did those adjustment was too eliminate one off expenditures that would not continue. And they didn't continue in 2014.
