On some firmware, the memtest efi binary trips up the firmware when loaded using the provided boot service LoadImage (for example by systemd-boot).

This is likely due to the PE optional header being too small (sbverify doesn't like this binary because of this). The efi binary can be fixed and made to boot with objecopy memtest.efi memtest-fixed.efi.

Grub does not exhibit this behavior as it presumably does not use LoadImage to boot.
