BBB will look for a valid MLO header on your eMMC and then use that MLO to load and boot u-boot on the eMMC. The standard u-boot environment will check if a SDCard is installed and if so load uEnv.txt from the SDCard. Usually u-boot will load the zImage from the SDCard, uncompress and run the Linux kernel and then mount the distro filesystem. There is no need to press the boot button. The purpose of the boot button is to load MLO and u-boot from the SDCard if there is something wrong with the MLO or u-boot on the eMMC.
