Did NIS America translate the full version of Secret Base or just the ending version for the Anohana blurays?

Title. Watching this on YouTube, the English lyrics are much better metered and closer to the rhythm of the Japanese lyrics. But if I look almost anywhere else, the lyrics are different, and are metered much more harshly and seem as if they're more literal translations, such as this one.

NIS America's translation feels a LOT smoother and I was wondering if they translated the full version or just the verse and chorus that's used in the episodes.
