Of course when reading over it in the regular fast way of reading through the comments, one might think there is a contradiction, because you said there would be one and so we read it that way. But there really isn't. It's an evasive manoeuvre. Of course they know what you're asking and they specifically do not want to lie and so they choose words you are going to very likely parse in a particular way.
If you think about it, is the "there's a contradiction in the following sentence" way of stating this any different/worse/better than the original? I would argue it isn't. Same level just on opposite sides of the argument.
