@kona5 Yes, definitely could be true.
Great seated vs. lying leg curl chart, credit to Stronger by Science team. Full article here: https://www.strongerbyscience.com/rom/
Seated leg curl (stretched emphasis) provides better growth for 3 of the 4 hamstrings heads. Lying leg curl (shortened emphasis) provides better growth for the sartorius. Both movements target the biceps femoris short head and gracilis equally (or, at least no statistical difference), as they're unaffected by hip angle.
Normally, seated leg curl is a nicer option in isolation, but I definitely agree lying leg curls are an awesome complement if someone's already doing a hip hinge that day, especially since RDLs are already a very stretch-heavy exercise. But both get the job done by hitting all the knee flexors.
The article also reminds me of the other nice benefit of leg curls which are targeting the sartorius and gracilis. They are rather small muscles, but combined, about the size of another hamstring head, and they aren't worked in hip extension at all.
