${=variable} doesn't always produce an array -- why?

["Bart Schaefer" <schaefer@xxxxxxxxxxxxxxxx>]

Is there any way to cause a scalar to be interpreted as an array regardless
of the number of words it contains?  Consider:

zsh% one="one"
zsh% two="one two"
zsh %echo ${${=one}[1]} ${${=two}[1]}
o one

This seems unintuitive to me.  I was expecting to get the entire word "one"
in both cases.
