Exactly this. In a Boeing if I want to descend at 1000fpm I can use V/S (thrust for speed, pitch for r.o.d.) or I can use FLCH or VNAV SPD (Pitch for speed, adjusting thrust for r.o.d.)
In either case the aircraft does the same thing because it's always a combination of pitch and power, the only difference is how you choose to think about it.
