Afraid it doesn't work. I've read the manual back to front to try something myself. Having transferred it to my mac and edited it there, the text boxes don't have the blue link boxes to link text.
Also, when transferring it back to the iPhone, when I open my document it gives a warning saying that linked text boxes aren't supported and it has separated them into two different text boxes again.
I'd suggest you give feedback to Apple about this as a feature enhancement request.
