Hi,

W.r.t. (3) below neither do I understand the sentence in question, nor
do I understand how the sentence could be interpreted such as to express
a difference to disable iff.

I have another comment:

It seems to me that 

w^{0..i-1}T^\omega|=P for i the least index,0 < i < |w|, such that w^i|=b,

and 

w^{0..i-1}T^\omega|=P for some i,0 < i < |w|, such that w^i|=b

are eqiuvalent.

The reason for this is that if i<=j and

w^{0..j}T^\omega|=P

then

w^{0..i}T^\omega|=P

This means that we can simplify the semantic definition to

  w|= accept_on (b) P iff 
  
   w|=P 
  or 
   w^{0..i-1}T^\omega|=P for some i,0 < i < |w|, such that w^i|=b

or equivalently

   w|=P 
  or 
   there exists i such that 0 < i < |w| and w^i|=b and w^{0..i-1}T^\omega|=P

Best Regards,

Johan
