Doesn't xsl:for-each-group over combined sequence solves the problem?

No, it puts groups in order of first appearance, which would put f before d.

How this is different from proposed solution:
(a, b, k, o, p, c, d, e, f, z, g)
where o appears before z?

Whether the answer should contain a minimal number of inconsistencies?
