Hmm...

grep -B2 snd /etc/udev/rules.d/50-udev.rules
# alsa devices
SUBSYSTEM=="sound", GROUP="audio"
KERNEL=="controlC[0-9]*",       NAME="snd/%k"
KERNEL=="hw[CD0-9]*",           NAME="snd/%k"
KERNEL=="pcm[CD0-9cp]*",        NAME="snd/%k"
KERNEL=="midiC[D0-9]*",         NAME="snd/%k"
KERNEL=="timer",                NAME="snd/%k"
KERNEL=="seq",                  NAME="snd/%k"


So... basically what you did is add the main /dev dir symlinks... 
Interesting...
