Dolphin won't overwrite existing saves in the memory card file, but it do write new saves to the file.
I'm currently running 4.0-6820, and i have moved the global memory card location to my secondary hard drive, it did overwrite the savefile one time after i made a new memory card file and transferred the previous savefiles, but then it stopped working again.
