What people don't understand is a chip fab is like an outsource printer. (Really over simplifying here) They really don't look at what they are printing they just output the files the customer gives them and check the registration. In this case the checksums. So there is also a very good chance that Samsung was not even aware that it was 64-bit or at the very least not true 64-bit. With all the different subsystems on the new SOC designs you can't really look at a chip and determine what everything is anymore.
I think most of us don't realize that even if Samsung would have access to all schematics of the A7 from Apple, they still doesn't own the right ARM licences for creating their own core like Apple did. Also, like you pointed out, you can't by only looking a chips under a microscope determine the ISA and all logical aspect of the chips.
The idea being that a 64-bit processor and Operating System is able to make better use of the systems RAM and processor and as such deliver much better performance.

There is a lot going with the new AArch64 improvement, a lot of legacy shortcoming of now archaic ARMv7 32bit architecture has been fixed and improved considerably, even a new 32 bit ISA (AArch32) has been added in the A7 to improve 32 bit codes performance.

"Apple kicked everybody in the balls with this," the Qualcomm employee said. "It's being downplayed, but it set off panic in the industry."
This is the best quote in the history of Apple reporting to come from the mouth of someone other than Steve Jobs.
