This really doesn't say much about a Series-A crunch.
It doesn't take into account the percentage of those companies who raised a seed round that were _seeking_ a Series-A round. This looks to me as if the article is making the assumption that 100% of companies who raised a seed round were seeking another around, and thus this year a smaller percentage of seed companies actually raised a round.
It also fails to mention whether or not the size of the average seed round grew. If you use HN and TechCrunch as anecdotal evidence, the trend seems to be much larger seed rounds the last two years. This alone could explain the fact that more companies are not actively seeking a Series-A within the first year.
