From what I understand (from conversations years ago back when ion was still in the planing/public consultation phase), the current (soon to be former) configuration of the tracks was relatively flat to about King, then there's a steep climb out toward Stratford. The grade separation offered an opportunity to smooth this out by raising the tracks at King. Imagine pinning the tracks at Park, though, and if that's the fixed "start" point, then that's great because the layover facility switch was moved over there. So the layover tracks can probably stay exactly as they are.
