When will this return anything but 1?

Never, but it saves a line at all four call sites, by having it return like that.

I could see how maybe people would prefer to just have it be a void function,
and return 1 directly at the call sites. Since this was a lower line count I
thought maybe it would be slightly better, but it's hard to say really.

It is a NIT perhaps but I feel like the signature of a function should stand on
it's own.  What this does is mix the meaning of this function with those
calling it.  Which IMO is not good style.

We can see what others say.

Sure. I'll plan on changing it to a void return type, then, unless someone else
pipes up.
