[R-SIG-Mac] R.app ?bug or me

I notice that 4.3.3 says"
"Finally it is possible to use a specific directory for a single
R session by dragging a folder onto the R.app icon. If R.app
is not runnig, this will cause R.app to be started in the
directory corresponding to the folder dragged. The same
can be achieved on the command line - for example
open -a R . causes R.app to be started using the current
directory as the startup working directory."
The final statement seems incorrect, at all events without
some further pre-conditions:
At the terminal:
ch2$ ls -lt .RData
-rw-r--r-- 1 johnm johnm 2980 9 Dec 11:31 .RData
ch2$ open -a R
At the R console that is started:
R version 2.6.1 (2007-11-26)
attached base packages:
 stats graphics grDevices utils datasets methods base
Incidentally is making copies of R.app an appropriate way to
allow multiple simultaneous sessions of the R Gui? Or is there
some more direct way to achieve this?
