I can't quote BS 5385, but to the best of my knowledge, osb/sterling board is not a suitable material to tile to, for that matter, no timber is.
It is too susceptible to external forces like heat/cold and moisture, even more so with a particle board.
And I certainly wouldn't swear by any technical description from B&Q/Trade-Point web site. They are two of the worst sites imaginable.
If your architect has spec'd 'Hardboard' technically that is also incorrect.
It would depend on his definition, it's ambiguous at best.
There are so many better options out there.
And tbh, if this mesh is as good or better than Ditra 25, why aren't we all using it?
Yes in certain circumstances it can add stability to a surface, but it is NOT a decoupling membrane, as was stated on your spec.
