As I have explained already, we derive the word order of the indirect question from the appropriate affirmative answer, which
may or may not match that of the direct question. The grammatical considerations which decide the word order of the affirmative answer, therefore, also decide the word order of the indirect question.
Sometimes they match...
1. Direct question: What is in his hand?
Indirect question: Do you know what is in his hand?
Affirmative answer (literal): Yes, I know what
is in his hand.
Informative answer (more usual): A stick
is in his hand.
Sometimes they don't...
2. Direct question: What is his name?
Indirect question: Do you know what his name is?
Affirmative answer (literal): Yes, I know what his name is.
Informative answer (more usual): His name is John.
Is this now clear?
