I guess mostly because you're spending less on them in overheads. When you can share the same overhead costs over 10 startups and expect 9 of them to fail, that's more palatable than spending the overhead 10 times for each individual company. And it's not just monetary costs: you can get more done when you have all the companies demo day together, simply by having to arrange fewer meetings individually, and less time travelling/setting up etc.
