The two feed directions are used for moving up to internal corners, you can move up to either internal corner so obviously two directions of feed.
If you apply all of your lathe tool knowledge it will make sense, you usually have two directions of lathe feed as well.
The edge that makes most difference to finish is the "lowest" tip of the tool, once this is damaged it doesn't matter which way you feed the tool, the finish will be rough.
Don't forget A shaper is much more useful than just a tool for making flat surfaces, think dovetails, machine ways, roller troughs and specialised form tools.
