TCP reassemble question

[Bo Xu <xubo.leo () gmail com>]

Hi guys ,

Wireshark can reassemble the tcp packets which is very cool feature.
For example ,If  the reassemble option is disabled in the
preference,  assume #9 and #10 are carrying the whole piece information
, there will be  these 2 prompt line in #9  :

Numer of bytes in flight :1460
Last frame of this PDU : 10

I would like to know how wireshark know these TCP segments are together  ?
