I think what you're asking is "Why use while when we know there can
only be one post on this view?".

I've seen plugins that hack the query to output multiple posts on
single/page views, so using while in a single/page template is a
little more flexible for people doing crazy things.

Also, always doing it the same way (which Twenty Ten doesn't) can
improve readability/reuse.
