how to repeat the last :[range]g with the same range?

I'm trying to redirect a :[range]g matches to a new buffer, then continue my work from there
here is some good examples:
http://vim.wikia.com/wiki/VimTip1063
the issue now is: it looks :g// only repeat last :global command without the range
how do I make even repeat with the same range?
this looks really useful if it can be implemented...

thanks!
