When using the Publicize feature with Facebook, since WordPress.com is directly submitting the information to Facebook, we mimic the og:description process (at least the typical one), which uses the Excerpt field if filled out.
Facebook has the option to check it against the site, and will use that if someone manually shares it, though best not to rely on that.
If you’re in need of a space for notes, I’d suggest using Custom Fields, since they would not be assumed to be specific data for any plugin:

I’ve disabled open graph tags using
add_filter( ‘jetpack_enable_open_graph’, ‘__return_false’ );
And built my own tags.
Are you saying that JetPack is directly submitting the content IN ADDITION to the Open Graph Tags?
If so, is there any way to stop this using a hook or filter?
Somewhat. Since the Facebook posting process happens between WordPress.com and Facebook, Jetpack has to create the information to post, which is done in a similar way to the same process that creates Open Graph tags.
We have this on the roadmap to iterate and improve upon.
In your particular case, Jetpack/WordPress.com is assuming that the Excerpt field is being used for the intended purposes (as would other plugins and themes). In the meantime, I would suggest using Custom Fields for non-excerpt information.
Thanks!
