It scrambles the file so whatever you program on the eprom matches the pinout you programmed on the program UI after programming the chip.

This would allow one to program a flash memory with scrambled pinout. You can't rearrange the pinout of a flash chip before programming as the programmer has to issue commands to the chip for the flashing to happen. Re-wiring would disrupt the flashing due to that.

It can't swap control lines, nor can it swap address with data. But l_oliveira is right about what it does: it scrambles the data within the file to make routing easier once the memory is soldered down. (Here, "routing" can refer to traces on a new PCB, or it can refer to rewire jobs when using flash memory in a slot for a mask ROM on a donor PCB.)

Download of version 1.2 in this thread works for me.

Version 1.0 (but not version 1.2) was also posted on RHDN.
