It’s worth taking a moment to explain why we are holding P fixed at P1:
To find out whether the AD curve shifts to the left or right, we need to find out what happens to the value of Y associated with any given value of P. This is not to say that the equilibrium value of P will remain fixed after the policy change (though, in fact, we are assuming P is fixed in the short run). We just want to see what happens to the AD curve.
Once we know how the AD curve shifts, we can then add the AS curves (short- or long-run) to find out what, if anything, happens to P (in the short- or long-run).
