Literally not that.
A good part of that article is talking about how final beer has a different mineral composition to the starting liquor, so Ca 163, Cl 262, SO4 90 in the water of one of Mike Tonsmeire's beers saw changes of -59, +186, +228 to end up at 104, 448, 318 in the beer.
If you were to take their numbers for Julius beer of 64/299/474 and assume the same changes, that would imply water of Ca 123, Cl 113, SO4 248.
Assume the same changes for Alter Ego ending at 34/421/336, and it implies the Alter Ego water starts at Ca 93, Cl 235, SO4 108.
Now of course you can't assume that the Tree House grists contribute the same minerals as Mike's beer, it _will_ be different but it gives you a feel for where they might be starting. Not having had either beer, I can't comment on what their mineral profiles might taste like, and there's always the caveat that the Julius and Alter Ego samples might have come from different sites (although from what one hears of Nate, one assumes he would be control-freaking about consistency for this kind of thing).
