Not sure which problem you mean it can help with? As far as I can see that 
is a quick approximation to convert WGS84 lat-long co-ordinates to Swiss 
projected co-ordinates, doing the datum transformation and projection all 
in one step via an approximated method. There are some more useful pages 
on the Swisstopo site though - we've had a little discussion about it on 
the PROJ.4 list over the past few days.
