They are both (un-normalized) probability density functions, as per the names pdfA and pdfB. My apologies if that was unclear.
To be somewhat clearer: I was referring to the probability distributions described by these two probability density functions. They have the same range, but disjoint support, and so anything you drew from B could not have been drawn from A.
In other words, a (pathological) counterexample to “The range of the distributions is the same, so anything you draw from B could have been drawn from A”.
