[target=Souca-target] Issue

Was hoping I could get some clarification on a change in macro behavior I noticed with 3.0.2. Prior to the patch a macro like the following worked without issue:

/cast [target=Souca-target,exists,help,nodead] [target=Souca,nodead] Lesser Healing Wave

Since the patch, this macro is behaving oddly and often failing silently. I tracked the issue down to this portion specifically:

[target=Souca-target]

Prior to the patch, this would take the target of my character, Souca. After the patch a /cast or /target will silently fail with this syntax. If I change it to use [target=party1target] then things work fine. What is really interesting is that the following line works:

/assist [target=Souca-target]

So has the ability to use a unit name in a target conditional been removed? Or is it only invalid when you want the unit's target? I'm hoping this is just a bug, but I wanted to bring it up to see if anyone else has dealt with it.

Thanks
