        Hi,
thread sorting has nothing to do with the format the message had been
received, it's only about Message-ID, In-Reply-To and References
headers.

The actual position of the message in the thread depends also on some
settings, namely those with 'thread-' prefix in
org.gnome.evolution.mail DConf settings. I see there these main two:
   thread-children-ascending
   thread-latest

The documentation you gave a link to describes default behaviour. You
can have these options changed, or you can have a different sorting in
the message list. I do not know. I only know that I didn't notice
anything like this myself (yet).
        Bye,
        Milan
