That's not quite what the OP wrote, nor what appears to be the text in MEL.
The MEL is a document created to enable a crew to deal with a single identified problem.
As the combination of items is endless, there cannot be a MEL in existence covering every combination of MEL items in existence.
... each MEL is only apply to one fault can not consider combined fault
The OP advised us that his MEL conform to this, as it cannot advise on combined faults.
It does seem somewhat unusual for only one defect per airframe to be allowable, as this would increase the likelihood of an AOG situation considerably.
Resultant of the MEL introduction being read properly, this is thus not the case, and the unusual is in fact usual.
There's absolutely no guarantee of that, without knowing precisely what the RTOW penalty is intended to achieve for each case.
100% agreed!
Unless we get shared the MEL items and aircraft type, we cannot make this assessment.
