See the definition of [[sym:yas-choose-value][=yas-choose-value=]] to see how it was written
using the two variables. If you're really lazy :) and can't spare a
tab keypress, you can automatically move to the next field (or exit)
after choosing the value with [[sym:yas-auto-next][=yas-auto-next=]]. The snippet above
becomes:
#+BEGIN_SRC snippet
<div align="${2:$$(yas-auto-next
(yas-choose-value
'("right" "center" "left")))}">
$0
</div>
#+END_SRC
