I suspect it'd be difficult to tell even if she could, because on some level it is ultimately just a fuel source, albeit affected by emotions.
Also, she confirms she's sundered in the Word of the Mother scene as well. My guess is that because she's still inside the primal but acting as its heart, the exact mechanism of it is different to how it affects a "regular" ancient and instead parts of the primal are segmented while the heart remains on the Source.
