It's not full blown mind reading. plan's are too complicated. Think of it more like martin taking everyone's perception of reality and using those to craft his own image. So he might see what you see, and feel what you feel, but he won't know what you are thinking.

Maybe he could have guessed as you weren't attacking with killing intend, but he was under pressure and hasn't been doing this for long after all.
