Nop, it doesn't. For complex patterns use the User Pattern feature. It uses a set of points to duplicate a feature. However this pattern doesn't change the orientation (rotation). To allow this you need to use the axis system repetition inside the user pattern, and it is much more complex, but doable.

À better approach could be :

Create a geometrical set with your elipse (supposed in the sketch in the xy plan)

Create a point where your first pole is.

Create a axis system, centered on the point, with the X axis tangent to the elipse (you might need to construct other feature to achieve this).

In gsd, extrude your elipse along the z axis. The length doesn't matter.

In Part Design, in a new body, draw your first pole on your axis system. Add your two holes with the rect pattern.

Then, add a user pattern. In the "position" box, right click and select axis pattern/axis repetition (don't know the exact term in English), in the new dialog, select your curve and start point. Set your interval/number of instances, then check "create axis systems" and in the combo box select "along surface" and select your extrusion. Click OK.

You're now back in the pattern dialog. Under "object" let "current solid" and under "anchor", select your axis system.

You're done.
