Probably because he is in LTRS state after he finishes the callsign +  
space part of the exchange, so he had to send a FIGS just before the  
599.

Lets say he is sending "NM4M 599 14" and does not have USOS set.

He would be sending (the numbers in parenthesis are for reference in  
the received text):

<ltrs(1)>NM<figs(2)>R<ltrs(3)>M<space><figs(4)>TOO<space>QR

If you have USOS set, your received stream (together with the shift  
state) would be

<<ltrs(1)>>NM<<figs(2)>>4<<ltrs(3)>>M<space><<ltrs(USOS)>><<figs(4) 
 >>599<space><<ltrs(USOS)>>QR

i.e., NM4M 599 QR

Take away the USOS state switches, non-USOS receiver would print

<<ltrs(1)>>NM<<figs(2)>>4<<ltrs(3)>>M<space><<figs(4)>>599<space>14

i.e., NM4M 599 14

Now, if you were NM4M/2, I would expect you to print "NM4M/2 TOO  
QR" (if I my guess about USOS is correct).
