new raids scrapbook

If Im missing few bosses from the original 50 guild raids and I join a guild that has 61 finished raids, will I get the missing bosses in my scrapbook when we beat the next raid?

I asked the same thing in another thread -- yes if you participate in one of the new raids you get credit for all of the original 50 in the scrapbook (confirmed by forum members).
