"why does it need an SD card, which the article implies is removable?"
That's actually one of the sanest backup ways to deliver updates in an unbrickable and also user-friendly way, if an OTA update borks the device for some reason. Most users would manage to download a file to an SD card and stick it into the vacuum cleaner if it went TITSUP (Total Inability To SUck Properly). The devil is in the details (and the haxxors in all your base) of course...
