Zsh doesn't do word-splitting by default on variable expansions:
$ zsh -c 'v="1 2 3"; for x in $v; do echo "$x"; done'
1 2 3
unless you set the SH_WORD_SPLIT option, or put Zsh in Bourne-compatibility
$ zsh -o SH_WORD_SPLIT -c 'v="1 2 3"; for x in $v; do echo "$x"; done'
$ zsh -c 'emulate sh; v="1 2 3"; for x in $v; do echo "$x"; done'
