From the wording of the T&Cs I'm pretty sure should a TOC to try and prosecute for invalid tickets they'd fail on a group of 3 with person 2 on both person 1 & 3s two together.
The wording says they have to travel together, doesn't say anything more sufficient to invalidate a group of 3 with 2 valid two together cards.
The T&Cs are too brief in my opinion.
