of
SA22-7832-11
*The eight-byte second operand in storage is used as the branch

the second operand are accessed, regardless of the addressing mode.*
I am thinking that it should explicitly state that the second operand
_contains_ the address to be branched to.
That's what it says.
However, your re-wording does read a little better. Why don't you send
it off to the manual creators?
Unless, of course, I am totally
misunderstanding what the instruction does. E.g.
*The eight-byte second operand in storage contains **the branch
address.
The branch address is subject to **the current addressing mode. All
eight
bytes of the **second operand are accessed, regardless of the
**addressing
mode.*
