Drive-by chiming in on this.

The reason CocoaPods has two copies of the lockfile is so that the versions of the installed dependencies (Manifest.lock) can be compared to the required dependency versions (Podfile.lock). This is needed for when the dependency dir is ignored from SCM and this is why that lockfile is located inside the dependency dir.
