I find this design pattern extremely irritating, but as someone who's done a fair amount of ecom/related web development I get it. There's very specific designs that 'scientifically' improve conversions, and the designers behind these systems often aren't the same people designing the software the service is actually selling. It's like the two groups have competing goals. There's definitely a middle ground between creating a system that's easy to sign up for/high converting, and a system that's easy to sign into/existing user friendly, but because of how companies staff, hire, and compartmentalize, there's often not the cooperation required to make that happen.
