Are the 4 Pets Welcome Lodging Combined Files (SW, SE, NE & NW) Updated?

 

Are the 4 Pets Welcome Lodging combined files (SW, SE, NE & NW) updated whenever one of the individual states' files are updated/corrected? By looking at the dates of the combined files it doesn't appear they are being kept updated whenever a change is made to individual states...

I only seems logical that whoever takes care of the files for individual states would update the combined files to keep them up-to-date.
