yes I know, I was just wondering if that was normal behaviour because it looks quite confusing to me. 

Personally I find it a natural way of expressing an empty interval.  to: is syntactic sugar for to:by:, and so the default of 1 for the step (the by: arg) is expected.

I'm dissatisfied however that I can't write $A to: $Z, or 1 to: Infinity positive (or 1 to: Float inf, ugh).

You have to say
