When you pour the beer into the glass sideways you are doing two things. You are increasing the surface area of the liquid which allows the carbon dioxide to escape faster and form less foam. As beer moves down the side of a glass it will spread out and move at a slower rate which causes less disturbance to the stationary beer. The act of pouring straight into the glass will force air bubbles into the beer (you can see this effect when you pour water from one glass to another) which also act as nucleation sites and allow more carbon dioxide to come out of solution.
