I'm pretty sure Asuna chose an Undine because none of the others chose a support class and a balanced party needed healers. There's no clear evidence that Reki alluded to the alliance in this case.

Edit: We do not encourage speculation on articles. If there's no proof or reference for the speculation (unless the speculation is done by the characters themselves), the speculation cannot be posted on an article.
