In the link above the article suggests its possible. Does it mean I have to buy the usb installation drive or can I download it and then install it on my other mac's

You can do the USB way if you don't want to redownload Lion in the mac store purchased which you can redownload it on other macs. As long you have youe purchase ID log in.

As long as you own them and some of them aren't used commercially, then yes.

Make sure you backup the installer before doing the first machine, or it will be deleted post install.
