If this assert is reached, `getSingleNonUnitDim(srcType)` returned true. Therefore, the source is guaranteed to have one non-unit dimension. This region also assumes dynamic offset, but that's not relevant for this assert, so I will move it before the offset check. Does this comment motivate the assert:
```
  // A source with exactly one non-unit dimension cannot be indexed directly by
  // multiple non-unit result dimensions.
```
?
