Isn't that doing both sides?
No.
There are two inward blocks at the beginning of the form, but that does not equate do "doing both sides". We can see this if we look at the position of the blocking hand just before the block.
In step 1, you are in a medatative position with your left hand over your right fist. Your right hand (the blocking hand) is
up. When we actually begin to move in the form, the right hand should move from that 'point of origin' position directly to the inward block position. This is called a "right, hammering, inward block". 'Hammering' is the method of execution.
In step 2, your left hand (the blocking hand) is
down, cocked at your hip. (correct?) As we make our second move, the left hand moves from its 'point of origin' from the left hip, up to the left inward block position. This is called a "left, thrusting, inward block". 'Thrusting is the method of execution.
To properly "do both sides", you would need to do both a: 'left, hammering, inward block' and a 'right, thrusting, inward block'.
Does that make sense? Can you think of any other actions in the form that would be different
if you were to start by Stepping back with your right foot?

Also, what are all these elbow strikes? this is CRAZY-different from the version I was taught.
Maybe not ... sometimes in American Kenpo we talk of dual action, or action within action. Often, when we begin to learn some of the moves in the form, our teachers deliberately choose not to point out some information, so that we do not become 'overloaded'.
There is always time available to revisit earlier information, and better define what is there, better explain what is there.
