Visible bit flag in layer record of PSD file format

Question

Hi
I'm parsing PSD files, and retrieving vitals about the layers they contain. One of the things I'm interested in is whether or not a layer is visible. The Photoshop File Format guide I have states that it is a "visible" flag, but based on the results I'm getting, it appears to be a "hidden" flag instead - i.e. it is 1 if the layer is hidden, and 0 if visible. Can anyone confirm if this is indeed a misnomer?
Thanks
Danny

Here is how I am using it. In full
There was a space on the original code.
property type_list : {"TIFF", "JPEG", "PNGf", "PICT"}
property extension_list : {"tif", "tiff", "jpg", "jpeg", "png", "pict", "psd"}
set nLayersName to {}
set matchList to {}
set matchLayer to "Shadows"
tell application "Finder"
  set HotDestination to (((path to pictures folder) as text) & "HotDestination")
  set HotFolder2do to (((path to pictures folder) as text) & "HotFolder2do")
  set HotFolderDone to (((path to pictures folder) as text) & "HotFolderDone")
  repeat with tFile in (get document files of folder HotDestination whose name extension is in extension_list and (name does not start with "50" or name does not start with "MJC"))
  set nLayersName to getNameOfLayers(tFile)
  set matchList to isMatchLayer(nLayersName, matchLayer)
  if item 1 of matchList then
  move tFile to the folder HotFolderDone -- move to subFolder A
  else
  move tFile to the folder HotFolder2do
  end if
  end repeat
end tell
on getNameOfLayers(f)
  set matchCmdStr to " | awk '!/kMDItemLayerNames|\\)/ { sub(/[ ]+/, \"\"); print }' "
  set mdlsCmd to "mdls -name kMDItemLayerNames "
  return do shell script (mdlsCmd & f's quoted form & matchCmdStr)
end getNameOfLayers
on isMatchLayer(psdLayers, matchItem)
  set matched to false as boolean
  set matchCount to 0 as integer
  repeat with layer in paragraphs of psdLayers
  if matchItem is in layer then
  set matchCount to matchCount + 1
  set matched to true
  end if
  end repeat
  return {matched, matchCount}
end isMatchLayer
