I can't say for certain, but possibly they asked about this in one of their monthly surveys. That or maybe they used a focus group or something. Personally I used the 30 second scan (and the Slide remote) so it doesn't affect me one way or another, but when I used to use the TiVo remote with my S3 (I switched to the Harmony), it frequently processed single button presses as double button presses. This made it tricky to actually get to ffx3 mode since it tended to cycle back to play. Back then I always resumed playing with the play button.
