Behavior of llLoopSoundSlave

I am messing around with llLoopSoundSlave and llLoopSoundMaster. It works fine when I start a master, then start the slaves.

According to the wiki at
http://rpgstats.com/wiki/index.php?title=LlLoopSoundSlave

"If a sync master is started when the slave is already playing, the slave will skip to the correct position to sync with the master."

However, I am not seeing this happen. If I start the slaves first, out of sync, then start the master, the slaves do not get back in sync. I have to stop them and then start them while the master is running.

Anyone else seeing this?
