Possibly pricing. Depending on the balance of logic vs I/Os you need, it could be cheaper to use two small FPGAs rather than one big one. Also if you're trying to keep the board simple by using TQFP rather than BGA packages, the MAX10 only come in a single pinout. So if you could combine two chips if you just had a couple more I/O pins, you're stuck. Or it could just be keeping the design clean and understandable, so if you rewrite the sound chip to try a new idea you know you're not going to lose video.
