You should confirm with each member of your group that they have a signed, witnessed and dated AD document, less than 5 years old. It is helpful to review the completeness and legibility of the document to ensure no mistakes have been made.
For each member of your group, check that copies have been lodged with the witnesses of the AD document, the emergency contact, the publisher’s GP, and the congregation secretary.
I too thought that the WTS was letting the "blood issue" slip into the shadows of history. These letters seem to indicate the complete opposite. At least now I can prepare in advance what I'll say when they ask for a copy of mine.
