Another Snort Rules Question

["Scott Elgram" <SElgram () verifpoint com>]

Hello again,
    I have 2 rules....(yes this is pointless and bad practice, I know, just bare with me here).

alert icmp 192.168.0.31 any -> 192.168.0.240 any (msg: "Test ICMP ping 1";)
alert icmp 192.168.0.31 any -> 192.168.0.240 any (msg: "Test ICMP ping 2";)

    Ok, I am 192.168.31 and I ping 192.168.0.240........In ACID I get 2 alerts.  One for msg: "Test ICMP ping 1" and 
one for "Test ICMP ping 2".  Now, I could be wrong here but I thought after a packet is shown true to a rule Snort 
stops comparing the packet to rules.
