Yes, that's my theory too. There's almost no street segments, you have vague reasons for going to Brookhaven to begin with, and afterwards you teleport to the Carnival, then teleport to the Church.
My guess is that the original plans were for you to start in the resort area:
>start at the motel
>go to Alchemilla
>go to the carnival
>possibly go to the church in old silent hill
Geographically, all these locations are close to one another, but in the final game Heather is teleporting all over the map in an awkward manner.
