well, it doesn't necessarily order the partitions in the same way as e.g.
rEFIt gptsync does, but that's because this GRUB implementation gives you more
control! You can even pick different MBR-partition-configurations, before
booting different OSes.
Yes it was written with such possibility in mind. I don't see why grub2 will enforce mbr partitions to be sorted since mbr doesn't require such thing. If you ask grub2 to put partitions in reverse order it does it. As to partition in zeroth slot it spans across the space before the first MBR partition and is so called protective partition and is required for some tools including grub2 itself to recognise gpt disk as such.
About compatibiliy: hybrid MBR is against specifications - it's a trick to boot legacy OS. So the only compatibility you can speak about is the ability to boot a legacy OS of your choice.

At least Mac OS X 10.3 and earlier don't understand GPT, and it actually makes
a difference with Apple's "target disk mode"! And there may be a few other
combinations.
Ok
