Hey ech,
I managed to find a workaround shortly after posting to your own question, here’s the link: http://support.advancedcustomfields.com/forums/topic/get_field-after-update_sub_field-gets-old-values/
My workaround method involves updating the lists field after setting the $list during the foreach. This way you you’re not forced in using WP code to access updated ACF repeater data.
