Consider a latex file aligned.tex:
\documentclass{article}
\usepackage{amsmath}
\begin{document}
\begin{equation}
\begin{aligned}
a & = b & c & = d & e & = f \\
\end{aligned}
\end{equation}
\end{document}
with six columns representing three separate equations on the same line.
When running latexml (LaTeXML version 0.8.2; revision 48de2c4) with
latexml --strict --verbose --nocomments --destination=aligned-latexml.xml aligned.tex
a padding is added to the every third column ('c' and '= f' in the example):
aligned-latexml.xml:
[...]

The expected behavior would be to add a padding to every odd column except the first.
