If anything I would say that is light! When running you will put 2-3x your load through your legs.
I'd also say not to get discouraged, the advice is correct but just like anything you can build up to it. Have you tried working through what 7, 8, 9, rpe feels like? The good thing about single leg is you can go pretty heavy as you have another leg to spot you!
I'd also say that heavy is better than high reps, so trying to get to 5 x 3 and then 3 x 5 reps at bodyweight with good form might be a more realistic near term goal
