PVS-Studio warning V501 for WebKit

ALWAYS_INLINE int
FEConvolveMatrix::getPixelValue(
  PaintingData& paintingData, int x, int y)
{
  if (x >= 0 &&
      x < paintingData.width &&
      x >= 0 &&
      y < paintingData.height)
    return (y * paintingData.width + x) << 2;
  ...
}

This is what should have been written here: y >= 0 && y < paintingData.height

This suspicious code was found in WebKit project by PVS-Studio static code analyzer.
Warning message is:
V501 There are identical sub-expressions 'x >= 0' to the left and to the right of the '&&' operator. webcore_platform feconvolvematrix.cpp 289
