Looking at the construction of that coffee maker, I noticed something: it's a percolator. It's got a tank of water that it boils, and as that water turns to steam, the pressure forces it out and over your coffee. It doesn't precisely set the water tank at, say, 190F and then pump it out over your coffee.
Water leaving the tank will be at or near 212F. I suppose they could say that the tube that goes from tank to the water sprayer is "precision engineered" somehow so the water cools in that tube by some exact amount, so it's in the high 190s/low 200s by the time it reaches the coffee grounds... but you can't really make that exact.
What you've got there is the delicious taste of confirmation bias.
