​I would think it would have something to do with the *In-Reply-To*
and *References
*headers. Message ID is unique to each message, not conversation.

For example, those headers for this conversation:

In-Reply-To: 
<cakvxacw3mxh0ufvjhwr8vvwmd4fdfsne+675_ts+pzy4av5...@mail.gmail.com>

References: <[email protected]>
<cakvxacw3mxh0ufvjhwr8vvwmd4fdfsne+675_ts+pzy4av5...@mail.gmail.com>​
