I wasn't expecting EITHER to be turned INTO a property - I was expecting
both methods to be the same, but one would have non-default properties
attached to it.

Ah!  That clarifies a lot.

Er, no, it doesn't.  What it says may well be COMPATIBLE with that, but
it is compatible with a good many other interpretations, too.  Until and
unless you know what it means, you can't extract its meaning from its
words.
