It works fine.

The documentation seems to be outdated regarding the alignment of
arrays. Arrays probably used to be aligned based on the size of the
entire array at one point (it's before recorded history, i.e. before
September 2000), or maybe the record field insertion code used to
contain some special (broken) logic for arrays that ignored their
alignment and instead used their size.
In any case, the alignment requirement of an array is and has been for
quite some time the alignment requirement of its individual elements,
and the alignment of a field's type is what's used to determine its
offset in a record (with a maximum of the current packrecords setting).
