No, it's just different words. If you host your site on the cloud, it's
obviously 'computing' too, since it involves computers. When they say "The
world's leader in hosting..." they are referring to our traditional managed
hosting business, where each client has dedicated devices.

Again, you're confusing the infrastructure with the applications that
can run on that infrastructure. Any app can run on dedicated servers located on
your company site, or on a nebulous network of cloud computing devices; that's
why I can now run the software for ProFox in the cloud without you noticing
anything. But the difference is that if a site gets super-popular (say,
slashdotted or mentioned on Oprah), your on-site system can't instantly expand
to handle the load, whereas with the cloud it can. To handle peaks like that
with dedicated boxes, you'd have to greatly overbuild, and most of that will be
sitting idle between those peak demand moments. With resources on the cloud,
you pay for the bandwidth you actually use, not the bandwidth that you think
you might need.
