Obb mount -o bind issue

So, I am on Android 4.2.2
I have the obb file in /storage/extSdCard/obb/ending directory
And want it binded in /sdcard/Android/obb/starting directory

So, I run in my busybox (jrummy apps)


#!/system/bin/sh
mount -o bind /storage/extSdCard/obb/ending/ /sdcard/Android/obb/starting/

But, I do not know why, when I run in my terminal emulator

ls /sdcard/Android/obb/starting

I get no output. Even though

ls /storage/extSdCard/obb/ending

confirms the obb file is there.
Why? Any ideas?
Many thanks in advance! :)
