Curious optimization of a reset circuit

I have seen a number of posts about creating a suitable reset.

The attached notes shows one successful attempt (testcase-2).

However, I am at a loss as to why testcase-3 fails.

I thought I would share my thoughts and notes to see what further advice could be provided by the wider community.

All the notes are in a PDF document (because I've included some waveforms from the simulator ... of RTL and of post-synthesis Quartus-generated files)

Any thoughts would be most appreciated.

Thank you.

I will need to discuss with the internal team related to the power-on-reset. Please allow me some time to work on it.

After discussion, we don't usually create POR as it is a part of the FPGA. 

I think the user guide below may help to explain how the power-on reset circuitry works in MAX10 fpga. 

Power-On Reset Circuitry 

Or you are asking about Asynchronous & Synchronous Reset design? Perhaps this paper may help to explain.
