Moving from Cyclone III to MAX10.

The pre-initialized memory is useful in some cases like:

1- Blocks that needs ROM memory. For ex, Numerical Controlled Oscillator (NCO). If you wanted to generate Sin and Cos values from the FPGA and sin and cos values are stored in a ROM.

2- If you used NIOS processor and the program is in an on-chip memory. The on-chip memory will be pre-initialized with the NIOS software.

The flash program memory of the max10 is not volatile of course.

I am sorry I did not try the method in the document of the remote update. I only program the FPGA with the JTAG only.

"so we can program it with jtag or "remotely" as the document implies?". I think the document explains programming with the NIOS processor and the programming files comes from UART interface which can be connected to external device.
