Sorry, if that garbling of text was my fault.   
   The a* in the last line of the quotation should have been -a.   
      
   To put the question another way:  if an electron with a hypothetical   
   exact spin vector p is subsequently prepared by presenting it to   
   to a detector with vector a (Alice's detector), then does the   
   electron exact spin axis p become changed to be exactly aligned   
   with vector a (or vector -a, whichever is appropriate)?   IMO the   
   electron spin vector after preparation  is either along exact vector   
   p or along exact vector -p.  The outcome of p or -p alignment depends   
   on which of p and -p is nearest in alignment to vector a.
