That's easy!  It's to mimic the preamble of the 
standard radiogram.

Go to 
for details.

>From that page, the datagram preamble consists of 

a. Number (begin with 1 each month or year) 
b. Precedence (R, W, P or EMERGENCY) 
c. Handling Instructions (optional, see text) 
d. Station of Origin (first amateur handler) 
e. Check (number of words/groups in text only) 
f. Place of Origin (not necessarily location of 
station of origin.) 

So, the SS exchange copies this almost exactly 
(leaving out the optional part c).
