If I remember correctly, the uboot provided on the stock eMMC image was configured to see if the SD card had a Linux kernel and load the kernel from that if it was there.  If the SD did not have a Linux kernel, it would fall back to eMMC.

Of course, if you’re willing to hold the boot switch, you can boot from SD without changing the eMMC.
