This is a common place in outdoor clothing and fabrics. Waterproof material is very resistant to moisture, however, where ever a hole is made from a stitch, gives water an entry point into the material. Taping the seams is an additional layer of material, typically inside the material to back the seams where the threads go, to prevent moisture from getting into the jacket, tent, or item. This is an additional barrier to protect the user. These are found on higher end products.
