Why drink pure water when all liquids get mixed up inside?

I don't see the point in "you must drink 8 glasses of *pure* water per
day" rule, because you can drink additionally any other lo-carb beverage
if you're at the end of the day meeting that 8 glasses requirement of
pure water.

So let's say I drink 8 glasses of water and in the meantime I drink two
glasses of strong tea. The stomach is one and only one, so all this
water and tea gets mixed up and at the end in there and it's the same
like drinking 10 glasses of strong tea mixed 2:8 with water creating
some sort of weak tea taste. Which still tastes better than pure water!

But drinking this mix is not correct, according to the "pure water" rule
followers...
They would say:
You *must* drink 8 glasses of pure water on top of those mixed glasses!

Absurd?

You be the judge... suggestions?
