The 'Up One Level' selection function has a couple of handy useages. For example, let's say you have a large Assembly open with lots of sub-assemblies and you wanted to select all of the components of a sub-assembly. Granted, you could go to the Assembly Navigator and find the sub-assembly there and select it that way, but you could also just select one of the Components in the sub-assembly and then hit the 'Up One Level' icon and it force the selection of the full sub-assembly. And if that sub-assembly was part of another sub-assembly, hitting the 'Up One Level' icon a second time would now select that sub-assembly as well.
The second most common situation is that you might have a group of objects, like say points that were Imported into NX using the new (in NX 8.5)
File -> Import -> Points from File... where you can create a set of points, whose coordinates were read from a text file, and they come in as a named group. Well if you wanted to select the entire group, you could just pick one of the points and then hit the 'Up One Level' icon to pick the entire group of points.
Anyway, this function has been around for years but most people never really learned what it was used for, but now you know...
