PVS-Studio warning V537 for Miranda IM

static BOOL ske_DrawTextEffect(....)
{
  ...
  minX=max(0,minX+mcLeftStart-2);
  minY=max(0,minY+mcTopStart-2);
  maxX=min((int)width,maxX+mcRightEnd-1);
  maxY=min((int)height,maxX+mcBottomEnd-1);
  ...
}

Most likely this is what should be written here: maxY=min((int)height,maxY+mcBottomEnd-1);

This suspicious code was found in Miranda IM project by PVS-Studio static code analyzer.
Warning message is:
V537 Consider reviewing the correctness of 'maxX' item's usage. clist_modern modern_skinengine.cpp 2898
