Grub defaults to installing to sda since that is the drive the computer typically boots from. Installing it to the other drive would result in it not booting unless you know to go into your bios and make it boot from the other drive, so this is very much intentional. If you really want to do that, then you can choose the something else option and select where to install grub to.
