All the confusions arise here are because People learned from the primary classes about question tags like..
-when "positive" statements come, then the question tag should be "negative"...and vice versa..
but here ...
this is another type of question tag..right?
I think,People need a more detailed explanation including me about these..
a)Positive >>> negative convertion of question tags..
b) same structure repeated as a surprising expression..like positive statement and positive question tag also followed by.

Some one please give an explanation for the different kinds of question tags..!

thanks in advance
