PVS-Studio warning V501 for WebKit

bool SVGRadialGradientElement::selfHasRelativeLengths() const
{
  return cy().isRelative()
      || cy().isRelative()
      || r().isRelative()
      || fx().isRelative()
      || fy().isRelative();
}

This is what should have been written here: return cx().isRelative() || cy().isRelative() || .....

This suspicious code was found in WebKit project by PVS-Studio static code analyzer.
Warning message is:
V501 There are identical sub-expressions 'cy().isRelative()' to the left and to the right of the '||' operator. webcore_svg svgradialgradientelement.cpp 253
