Were stimulus payments for dependents reduced for incomes above $75,000 similar to how the main payments were?

I've seen where the main payments (ex. Round 1 $1,200 and Round 2 $600) are reduced $5 per $100 over $75,000.  I'd like to confirm if dependent payments (ex. Round 1 $500 and Round 2 $600) worked the same so a single dependent would be eligible for a Round 2 dependent payment of $400 if AGI was $79,000.
