Huge difference between a split duty accomodation requirements and the requirements for a four hour airport standby.
Airport standbys have been around for well over thirty five years in various parts of the world to my certain knowledge, possibly a lot longer. Always considered to be the thick end of the wedge, rather than a twelve hour standby at home and being called in the last hour etc. Airport Standby = four hours of chatting to anyone around in the crew reporting area, where comfortable furnishings need to be provided plus tea, coffee etc. then off home, finished! Either that or you are off on a trip somewhere which beats stand-by anyday, just be aware of which flights you are covering and what you need to have with you by way of crew baggage, just in case. If you do 06:00 to 10:00 and don't get called you have effectively got a day off rather than another eight hours just hanging round at home/on mobile etc.
Give it a couple of months and you'll be enjoying it!
