One reason is, its there ready to serve a new request. If there is no instance running, one will have to be spun up, adding (possibly significant) delay to the next request.
With 15 minutes Google appear to be offering a compromise. It's probably not totally arbitrary number, but based on something like 'average time between requests' on a lowish traffic website. Also spinning up an instance isn't free (for Google) - eg your codebase has to be transferred to the node (unless it already has it) - so the 15 minutes delay is in part a 'spin up fee' - to cover the cost of instance startups.
