Question NBC Sports Live Extra app creates /storage on /sdcard

I noticed that I have multiple storage/emulated/0 directories in sdcard. I reboot'ed in recovery mode to make sure no symblinks or bind mounts were involved, ran find and it seems like the NBC app created all those directories to save its data. Has anyone else experienced this?

Code:
adb devices
List of devices attached
HT3XXXXXX    recovery

...

mount
rootfs on / type rootfs (rw)
tmpfs on /dev type tmpfs (rw,seclabel,nosuid,relatime,mode=755)
devpts on /dev/pts type devpts (rw,seclabel,relatime,mode=600)
proc on /proc type proc (rw,relatime)
sysfs on /sys type sysfs (rw,seclabel,relatime)
selinuxfs on /sys/fs/selinux type selinuxfs (rw,relatime)
/dev/block/mmcblk0p36 on /cache type ext4 (rw,seclabel,relatime,data=ordered)
/dev/block/mmcblk0p37 on /data type ext4 (rw,seclabel,relatime)
/dev/block/mmcblk0p37 on /sdcard type ext4 (rw,seclabel,relatime)
