Because it's not a range as in low-high #.
Emanon-R1(config-route-map)#class-map Who-Knows
Emanon-R1(config-cmap)#match ip rtp ?
<2000-65535> Lower bound of UDP destination port
Emanon-R1(config-cmap)#match ip rtp 16384 ?
<0-16383> Range of UDP ports
Emanon-R1(config-cmap)#match ip rtp 16384 16383 ?
<cr>
Emanon-R1(config-cmap)#
So you give it your starting point and then the number of ports (e.g. 16384
+ 16383 of them = 16384-32767)

Subject: Matching VOIP packets in a class map
Hello group,
I am confused about the proper way to match on voice packets in a class map.
According to Odom's QOS book, he often uses the following commands:
class-map match-all voip-rtp
match ip rtp 16384 16383
Is he specifically matching only 16384 and 16383 or is he matching a range?
Why does he place 16383 before 16384?
Thanks
