Not knowing what the plant would normally look like under strong light, I can't rule out etiolation. Strong light will certainly give a more compact plant, all things equal. That is an important and useful general rule, especially in the northlands. Aloe juvenna would not look like that if it were etiolated, though... the leaves on juvenna are more triangular in shape (wide at the base) and they are packed closer together along the stem even under suboptimal light, and the stem itself is actually quite robust in comparison, thus tends to be pretty stiff, at least at the base.
There's a bunch of sideways growing aloes with creeping stems that I know close to nothing about (too many aloes, not enough time). I have mostly ignored those chapters in my aloe book.
