It is pretty typical for an investor to pronounce one thing and then do something totally different.
Investors are driven by the "feel" of the opportunities they get to look at and any pronouncements "we are funding this, not this" are merely looks in the rearview mirror. Trying to read the investors' minds and predict their actions is a lot like Kremlinology, it is best to focus on building a solid business and not worry about their opinions too much.
They didn't do that. The original article was one of their partners saying they weren't doing as many consumer Series As anymore, and were shifting toward doing A rounds for enterprise companies and B rounds for consumer.
A bunch of commenters on Hacker News misinterpreted the article as "A16Z isn't doing any Series As", so Marc Andreessen jumped in himself to clarify their original point.
Now it's being misinterpreted again. Read the original article and Marc's comments--they've been consistent with this message the entire time.
