To be fair, there's nothing disrespectful about taking a penalty in a way that increases the likelihood of scoring.
It might look unconventional, but it divided the keeper's attention between two players and it went in.
It's the same as knocking it down the centre. It works if the keeper has dived to the side. Otherwise, it doesn't. Why is it disrespectful?
If it was generally considered a more likely method of scoring a penalty, more teams would do it.
