I think a good reason is when you hvae a large system to write.
I person does the design, and writes thes specs.
He the writes a basic flow, while others may write  the implementations.

It was perhaps more important in the days before good version handling syst=
ems.

But still, it is a useful feature, just as separates are.
When many people wants to change in the same file, separate some functions =
may help.
And they are still visible in the body.
