If your Mac is at all modern & sports a T1 or T2 chip, that'd be why - Carlos was mostly active in the hackintosh scene, and both of his PE packages are front-ended by loaders that are meant for the common PeeCee and can actually be quite hostile to the true fruit. In the past, there have been multi-utility boot discs made up - usually by paring away all the flurff so that what was left of the OS & a handful of apps could be burned to a 4.3 GB DVD-R. I've also seen products make leverage of BaseSystem (the heart of Recovery and the OS installers) - Alsoft comes to mind as an example, they include a 'Recovery Maker' app with their DiskWarrior that will pull down a Recovery image, then shoehorn the DW app into it and spit out a bootable USB-stick just for that Mac.

You can format and install macOS onto any flash drive just like an external hard drive. Boot it up and add in all utilities you think you need. Store it and boot it up when you need help.
