Proof step 29 from proof path-equiv-reach (previous step)

(a ' + y0) .last = y1 .last, # y1 = # y0, reach(a, y1 .last, # y0), path(a ' + y1 + a0 '), path(a ' + y0) ⊦ reach(a, y1 .last, # y0) ∧ a0 ∈ succ(y1 .last)

And obtained the following new goals

Proof step 28:
(a ' + y0) .last = y1 .last, # y1 = # y0, reach(a, y1 .last, # y0), path(a ' + y1 + a0 '), path(a ' + y0) ⊦ a0 ∈ succ(y1 .last)
