I took the same meaning as you, hitoshura. Besides, water pervades the room even if it doesn't exactly occupy the total volume of it.
Anyhow, to tell the truth, I never really thought about the nature of what Genesis was chilling in there, either, but -- with all the thematic crap that's gone on between Genesis and Sephiroth already -- I wouldn't be at all surprised if that sphere was mako as well.
*Crisis Core spoilers*
-Sephiroth was exposed to Jenova cells as a fetus. Genesis, while a fetus, was exposed to the cells of a woman injected with Jenova.
-Genesis went pretty batty after learning his origin. Sephy did too. Both seemed to think of themselves as superior beings, as well, though for different reasons.
-Genesis fancied himself as fit to inherit the goddess' gift. Sephiroth fancied himself fit to become one with the planet (which the goddess seems to be an embodiment of).
-Genesis ultimately decides to become the planet's protector (conveniently not doing a damn thing during the Meteor crisis, of course). Sephiroth wants to hijack the planet as a tool for his own desires.
-Sephiroth has an angelic black wing on his right side. Genesis has a slightly more demonic black wing on his left side.
-Sephiroth regenerated inside a mako crystal. Genesis seems to have hibernated inside what may be a mako crystal.
Thematically, it fits.
