This is an interesting issue---I thought lowdown was doing the same as other systems, but pandoc shows me otherwise too. It seems that I inherited "strict" mode from Hoedown, which matches between blocks, whereas the existing parsers simply do one tag at a time. I'll look into this, thanks for reporting.
