I think so? I took a "basic" class from a German woman (who did apologize to us for probably confusing us for life!) who was teaching some version of continental, and then I spent many years (pre-youtube) messing around without patterns or from very old books, and then when I decided to try to level up and knit things that were not just tubes or rectangles with very simple increase/decreases, I was using Icelandic patterns. So I think I default to something similar, but not identical to, combined knitting. I tried to teach myself American style a few years back, but I'm not sure I was doing that right either, so I stopped before I learned a different set of bad habits. And I found it a lot harder on the wrists and fingers, too, so I wasn't super invested in retraining.
