No this is only hype and not true.  It is more of an urban legend.

Potentially it might be able to move an extent to another "asm disk".
But I haven't even seen that demonstrated anywhere.

ASM disks are not disks they are whatever you give ASM to use.  It you
are using EMC direct attached you get LUNs from EMC.

You can give that to ASM.  Does ASM really have a disk?  Of course not.
