No, it means that .NET 4.6.1 supports .NET Standard 2.0 but not 1.5 or 1.6; .NET 4.6.2 supports .NET Standard 2.0 and 1.5 but not 1.6, and .NET vNext will support all of 1.5, 1.6, and 2.0.

It also means that there are APIs in 1.5 and 1.6 that do not exist in 2.0. Seems to be a combination of deprecated without replacement and things that will be revisited for later 2.x versions. (Which is semver compliant, for what that is worth.)
