i haven't seen those fights, but i am preety sure the submission thing was bean punching his opponents and them tapping. he has a couple of chokes, but those are probably elbow chokes, all those submission victories were over ultimate cans.
even bean admits it, he said something on the line of, i couldn't do anything in the ground before but after training i atleast know how to stand up from the ground so i don't get into trouble.
bean's ground game is not good at all, records don't tell you what a fighter can do, especially when he has fought people in their debut matches...bean would stand up with hunt for sure and he would get decimated.(IMO)
