It didn't mention whether or not the air was brought back into the capsule or not, but as it described the suit was filled with oxygen.
According to this source, it was pure oxygen, at least in his suit. The capsule was another matter.
I believe Leonov did nearly die; after all, he had to depressurise his suit to a dangerous level to get back into the spacecraft.
He reduced the pressure from 40 kPa down to 27 kPa. This is not a dangerous level, it is more that the Apollo EVA suit (25.5 kPa), and 50% more than the safe minimum for any suit in an emergency (e.g. 18.5 kPa used by by the Shuttle EES).
