I already explained it. I think you need to read the answers a bit
slower. I'll say it again here:

remote_array is a DRbObject. Methods called on it are executed on the server.
remote_array[0] is regular, local, array. Methods called on it are
executed on the client.
When you do things like:
  remote_array[0].length
  remote_array[0][i]=whatever
  remote_array[0][i].reverse

all those things are executed only in the client. The reason is that
the first thing those snippets do is remote_array[0] which returns a
regular, local array. Everything else after that is just in the
client. That's why you never see the changes at the server side.

Jesus.
