It depends on the format of the flash files. If you generate an srec (the default with elf2flash) or an hex files, they contain both the data and the address it should be written to in the flash. The --after option just ensures elf2flash starts the address just after the FPGA image. If you convert those to binary files before you concatenate them I don't believe the --after option makes any difference.

Did you try to read back the flash contents and compare with what the Nios II programmer writes?
