Hi. I've worked for WordPress.com for the past five years. It does run the open source WordPress codebase, and we sync changes from the open source project to WordPress.com regularly.
Yes George. WordPress.com is a centralised, multi-tenant application which also syncs code from the open source project. Very good.
It's still not equivalent to running the same code, or being in any way a comparable to a managed host. Which is the point that you skipped right over, as is your custom :)
