Thanks.

I redid the examples with the autostrut parameter set to respectively yes and no. In the former case I see all have an hbox and in the latter case all have a vbox. So it seems not the align, but the strut being the one determining the box variant.
No, the align settings determines the box type. The \strut at the begin forces horizontal mode which results in both \hbox’es in the same line.

Ok. But when using "strut=no,autostrut=no" I see for all values of align the abc/xyz below each other and none having abcxyz. Doesn't that suggest that all boxes are vbox and that the strut merely forces horizontal mode? Otherwise I do not understand what happens.

Thus I did the experiment again, for all options with \framed[strut=no,autostrut=no,align=OPTION]{\ifvmode V\else H\f.
I  found a V at the front of the output in each and every case.
