Please do not read too much into that.  It is not formally a distinct
namespace in the W3C RDF sense; schema.org's namespace is flat, the
extension/subdomain extension structure is an organizational view into
a (fairly :) unified whole. The URI for the term is

As we say in that page,

"The schema.org medical vocabulary was originally created in
collaboration with WikiDoc and others. Recent improvements including
the migration into the health-lifesci extension has been led by the
Healthcare Schema (schemed) community group at W3C. The health-lifesci
schema.org extension is available for other collaborative schema.org
extensions in topics centred on healthcare, medicine and the
lifesciences (e.g. see also Bioschemas, and the pending proposals for
describing US healthcare insurance networks)."

This makes clear that this section of schema.org is intended as a home
for medical and healthcare terms but also those from the broader life
sciences, which would make #1 a reasonable reading.

I think so.
