Does drinking water inbetween drinking pop help your teeth?

Say I take a drink of pop, then take a drink of water immediately after, and even maybe swish the water in my mouth a little... does it help prevent tooth erosion and even bacteria growth by washing away the sugar in my mouth from the pop? Fluoride is also an additive in our local water. I've been doing it lately and i drink 2 or 3 pops a day on average, and IMO it seems to be helping, Is it just in my head? i usually drink about 25% more water than pop when doing it.
