[texhax] Strange alignment in memoir+gather

This seems to be almost minimal example as effect is extremely
unstable and disappears as some parts of formula are removed. I have
observed this effect before in some occasions but cannot figure out
any patterns


\documentclass[12pt]{memoir}
\usepackage[leqno]{mathtools}


\begin{document}

\begin{gather}
|D^\alpha D_{(z)}^\beta K''_{jk}|\le
c_{\alpha \beta }\mu ^{-|j-k|} \nu \qquad \text{for\ \ } j\ne k
\tag*{$(7.4.48)_1$}
\\
|D^\alpha D_z^\beta K''_{jj}|\le
c_{\alpha \beta }\mu ^{-2}\qquad \text{for\ \ } j= k ;
\tag*{$(7.4.48)_2$}
\end{gather}

\end{document}




Another snippet:

\begin{gather}
|D^\alpha D_{(z)}^\beta Q_{(l),jk}|\le
c_{\alpha \beta l}\mu ^{-\max (M+l-1,|j-k|)} \bar{\nu},
\tag*{$(7.4.45)_1$}
\\[3pt]
|D^\alpha D_{(z)}^\beta Q_{(l),jk}|\le
c_{\alpha \beta l}\mu ^{-\max (M+l,|j-k|)} \bar{\nu};
\tag*{$(7.4.45)_2$}
\end{gather}
