Throw Fire/Ice/Thunder Rod Glitch

In a clean new rom, and by default, Fire/Ice/Thunder Rod cannot be throw. But doing so, not only allow multi-target the enemies throws, but moved Shadow a couple of steps forward and will remain in the same spot where he threw the rod. Anyone notice this? And any patch to fix? 

Side Note:
I do not remember what I patches I had applied to my hacked rom, but now throwing Gravity Rod will also result in multi-target the enemies, and moved Shadow forward to a new spot.
