Of course, this "out of spec" behaviour of DRAM, more specifically the ability to do copying, is also implicated in this infamous bug: https://news.ycombinator.com/item?id=5314959

The 'et al.' is used for in-article citations, if done in author-year format; references in the reference list are, to the extent that I've seen, always written out in full. I guess Google just wanted to make the life of any academic citing their work miserable. There are (unfortunately) conferences that have page limits that include the reference list; I wonder if an exception would be made here.
