The limitation of 2 buy-sell transactions and no overlapping buy-sell transactions are orthogonal. My solution listed 3 buy-sell transactions, but none of them

The limitation of 2 buy-sell transactions and no overlapping buy-sell transactions are orthogonal. My solution listed 3 buy-sell transactions, but none of them are overlapping. Edit: I see now that it says "two no[sic] overlapping" trade pairs, which invalidates my solution.
