Your "Alignment Tech" is crazy
and he is making this way more complicated than it is.
If your tech had actually removed & inspected the steering wheel.
He would have quickly found that...
The splines on the steering wheel & steering column allow for full indexing adjustment of the steering wheel.
The steering wheel does NOT "only go on one way".
There is no keyway on the wheel or column splines.
The alignment should be set , then remove the steering wheel & re-install it in the proper position on the column.
