This is not true and there are other scenarios that can and do come into play that can require the Host OS to gain Internet Connectivity via the Guest! One personal example that comes to mind when I was first using a Mac I had a Motorola Cell Phone that could only connect/tether to Windows and at times I'd tether the phone to a Windows Virtual Machine and gain Internet access on the Mac Host via the Windows Virtual Machine using the tethered Motorola Cell Phone. Try thinking outside the box sometimes!
