Well, at first the documentation only mentions horizontal borders to be 
the maximum of both elements but nothing that this also applies to 
vertical borders. It says:
-------------------------------
The horizontal space between two controls (LeftControl, RightControl on 
Parent) is the maximum of ...
-------------------------------
But no words about the vertical alignment.

And second that was my experience too. But I just tried it again on a 
fresh project and now suddenly vertical alignment behave the same! This 
"eratic" (unpredictable, at least to me) behaviour was the reason I 
wanted to look into the documentation but it did not make it clearer but 
more obscure. It seems I have to invest much more time into this than I 
wanted...
