Anaconda option "nogpt" is supposed to force MSDOS type partitions to be created. However, if installer is initially booted in EFI mode (e.g. MAC) then nogpt option is actually ignored and GPT type partitions are created during installation process. People expect that "nogpt" option will be honored regardless what mode (EFI or BIOS) installer was booted. Simultaneously nogpt created installation should create regular (non efi) installation because efi cannot be started from msdos partition, even if installer is booted in efi mode. Tested on F19,20,21. Another issue is that "nogpt" option has a confusing name. I would much prefer an option with more consistent names, something like partition_type={MSDOS,GPT_BIOS,GPT_EFI}

I am not sure the bug 978430 is related to this. I am writing specifically about nogpt option, which stopped working around F19 Was before: if nogpt option present - create MDDOS partition and regular installation. Currently: nogpt option is ignored, regardless or nogpt option - gpt partition is created with UEFI installation. Please give working nogpt option back

It was removed in Fedora 18, because that was the point where anaconda switched to using the msdos disklabel by default, excedpt in the following cases: the inst.gpt parameter is specified on the command line, or the installer is booted using EFI. You are doing the second. We do not support installing to a msdos disk label from an EFI install.
