Yes, that is how the preinstalled version is set up to work, i.e., boot first from SD card.  This is stated to be temporary through a temporary boot file.  Permanent opertion is to boot first from the eMMC.  The system is constructred to run off the eMMC memory not an SD card.  SD card is for extra storage if needed.  Why put installed memory in if it is not to be used.

That's not true. I've flashed Manjaro Phosh to the eMMC and it still boots from SD Card if a boot image / distro is detected. If there isn't a boot loader / distro on it, it will boot from eMMC and use SD card as storage. In fact you can boot from SD card by holding down power for 5 seconds, or internal when holding down power for 2-3 seconds.
Most distro images for Pinephone Pro include the boot loader setting SD card as highest priority. I'm not sure what you are talking about.

To recover from a corrupt bootloader (partial boot) soft brick, you simply need to insert the SD card, press the RE pinhole on the back of the phone, and press power to boot to SD card. This forces SD card boot by temporarily cutting off eMMC access, once booted the eMMC will initialize so you can fix it by overwriting it with a clean image. Holding RE during boot for more than 3-5 seconds causes it to boot from SD card, but not initialize eMMC after boot.

All this information is outlined in the wiki. I'm not understanding where the confusion is.
