Thank you for the visualization. I find the height offset aesthetically acceptable. From the outside even more than from the inside, since there is more wall up to the corner and from there again to the next window.
Because one element is landscape format and the other portrait format, they look unequal anyway. Then rotated 90° to each other. So edge alignments do not stand out that much visually.
By the way, the fact that top edge alignment would be extremely important on the upper floor would be needed to explain why different bottom edge heights are obviously not a problem?
Personally, what bothers me the most is the light strip in the basement between the two floor-to-ceiling windows: on the same wall and no edge alignment anywhere. Compared to that, the upper part is really no big deal...
