There is no bug. Please read the "Constraints" section of:
http://www.w3.org/TR/xsl11/#fo_repeatable-page-master-alternatives
the key part: "(d) that alternative is the first alternative in the
sequence of children for which all the conditions are true"
That means you have to put most constrained alternatives first and the
more general ones after that. In your example, there is only a master
reference for the first and the last page. The FO processor then doesn't
know what to do with the other pages in between.
If you need special page-masters for the first and last page, you have
to do something like the following. Note again, that the order of the
conditional-page-master-references is important. For the third I've
omitted the page-position property because it defaults to "any".
<fo:repeatable-page-master-alternatives>
<fo:conditional-page-master-reference master-reference="first-page"
page-position="first"/>
<fo:conditional-page-master-reference master-reference="last-page"
page-position="last"/>
<fo:conditional-page-master-reference master-reference="normal-page"/>
</fo:repeatable-page-master-alternatives>
