Definitely possible.I think you're parsing words unnecessarily.
However, Civ V has always been strict with the distinction of building and buying/purchasing stuff. Maybe it's just "poor wording" in a press build. OTOH it could mean that science buildings are not directly available like with a "normal purchase". Especially since science is crucial in Civ, and we had already some discussion if this direct purchasing of science buldings could be too strong or not.
