PVS-Studio warning V501 for QuantLib

Distribution ManipulateDistribution::convolve(
  const Distribution& d1, const Distribution& d2) {
  ....
  QL_REQUIRE (d1.xmin_ == 0.0 && d1.xmin_ == 0.0,
              "distributions offset larger than 0");
  ....
}

Most likely this is what should be written here: d1.xmin_ == 0.0 && d2.xmin_ == 0.0,

This suspicious code was found in QuantLib project by PVS-Studio static code analyzer.
Warning message is:
V501 There are identical sub-expressions to the left and to the right of the '&&' operator: d1.xmin_ == 0.0 && d1.xmin_ == 0.0 distribution.cpp 281
