hi bbar that wont be ABX in that case and wont be double blind, re cola test have a read to description including that example I posted in thread above. the pepsi challenge is a single blind test, not ABX or double blind.
the whole basis of ABX is the evaluator knows clearly which is A and which is B, theyre the reference samples. its X who the evaluator doesnt know the identity off and needs to compare back to A & B to decide. dont give them a chance of that and they wont have a hope in my opinion. even in pepsi challenge the evaluator can take as many sips of A and B to decide.
if the person conducting the test knows the identity of X while conducting the test it isnt double blind.
but again as mentioned you do whatever you see fit to come to your conclusions
its what happens in the real world every day, be it just individuals or multi million dollar billion dollar businesses. people make all sorts of calls using what basis they see appropriate

This should fit definition of double blind.
Agree it is not ABX .
It is - Is A different or same as B and evaluator has no idea which is A and which is B
