Yes, that's how it was intended. The only benefit of marking something as an esm is when you have loads of script references like in e.g. DLC sized new land mods, which in this case it doesn't.
Thank you very much for porting these mods to Oldrim, this is highly appreciated, I'm in the middle of a playthrough right now, but I'm downloading it for a future profile, thank you again, take care,
