Because you are not thinking of the problem in the correct way.  Received
headers are added at *every* server stop along the way. Thunderbird 
delivers as
follows:
Thunderbird client --> Mail server
One hop -- one header.

IMP delivers as follows:
Web browser --> Web server --> Mail server
Two hops -- two headers.  This is our behavior.
