The original PinePhone (unlike the PinePhone Pro) does not have an SPI flash dedicated for booting (the text in your link that claims you should install the Tow-Boot to the SPI on the PinePhone is wrong, the accompanying screenshot is from a PinePhone Pro), so Tow-Boot is installed to the eMMC or to a microSD card. Which means that if you install a distro which comes with its own bootloader (usually its own build of u-boot) the common way (by overwriting the eMMC or microSD card contents with the distro image), you will be overwriting Tow-Boot with that distro's bootloader anyway. So it should not matter at all. (And besides, those distros normally boot just fine with Tow-Boot too.)
