Comment (by pwaara):

 Another clue.  The variations that are losing their association to the
 specific attribute have a slash (/) in their name.  That is, the name of
 the custom attribute is "Available Styles/Sizes".  All products variations
 that use this custom attribute have "Any available Style..." after the
 update.  I copied one of these products, created an identical custom
 attribute except I named it "Available Styles and Sizes" and did the
 update again. The product with the custom attribute "Available Styles and
 Sizes" was unaffected.  The product variations with the slash in their
 custom attribute name lost their assigned attribute again.
