"At this point" is key, actual copying was important earlier in this case but is now a decided issue.

This appeal is strictly about the copyrightability of APIs. The supreme court generally doesn't address cases as a whole, but specific issues brought up to it on appeal.

If I remember the decisions on the actual copying part of the case correctly, it was decided that Google copied something like a dozen lines of uninteresting code directly (not api's, just some method implementation), and that this was de minimis copying and didn't constitute infringement. You should check if you really care though, I might be wrong.
