You are right.
I looked through the source code:
Because the last "load" write the image into flash, which means the values
of "entry_address/load_address/load_address_end" are not located in the
"ram_start - ram_end" region.
So these values are treated as invalid in fis_create() function.
I use the commands below and it works.
"fis create -f 0x80040000 -l 0x000C0000 -n twothreads"
"go 0x80040000"

You probably need to pass all the parameters. Eg the example in the
documentation at
http://ecos.sourceware.org/docs-latest/redboot/fis-create-command.html
is
fis create RedBoot -f 0xa0000000 -b 0x8c400000 -l 0x20000
ie load it into flash at address 0xa0000000 from RAM address
0x8c400000 with 0x20000 bytes of image data.
