Indeed. I'm confused by this line from the article

> a study with 197 participants, the team could infer the identity of persons with almost 100% accuracy – independently of the perspective or their gait.

The paper seems to make it clear that the technique still depends on gait analysis, but claims it's more robust against gait variations.

The paper also makes clear they had no success correlating across different perspectives- welcome to science reporting.
