I don't know how long you have followed Alex, but he was very reserved in this interview compared to many others in his past. Even so, yes I observed the mistakes you heard also.

It is a combination of his passionate personality, and the fact he is burdened with the big picture. Didn't you notice the fear and trepidation in his voice? He is freaked out. He does this every day and also don't forget, he is still young. (47)

Cut him some slack? He provides you with alot of variety.
