When stdout and stderr both go to the terminal and haven't been
messed with, there is a synchronization that happens.  Each line is
written by a single shell process without buffering, and the result
is that things appear in the correct order.

Filtering one or more of these streams through a background process
means you lose that synchronization.  You have two independent processes
which are both writing to the terminal, and they don't wait for each
other.

I showed examples of this in my previous message.  You're seeing the
same thing.
