Yes. It matches the whole absolute path.
```scala
scala> val fs = java.nio.file.FileSystems.getDefault
fs: java.nio.file.FileSystem = sun.nio.fs.MacOSXFileSystem@782dc5
scala> fs.getPathMatcher("glob:/x/1.dat").matches(fs.getPath("/x/1.dat"))
res0: Boolean = true
scala> fs.getPathMatcher("glob:/x/*.dat").matches(fs.getPath("/x/1.dat"))
res1: Boolean = true
