That's unfortunate.  It definitely seems like that should have worked.

On my 10.9.5 system, the last location is remembered in the defaults for 
TextEdit.  The command "defaults read com.apple.TextEdit 
NSNavLastRootDirectory" provides it.

I think you should override -runModalOpenPanel:forTypes: and 
-beginOpenPanel:forTypes:completionHandler:.  In each, you would customize the 
Open panel by setting the directoryURL property and then call through to super.
