This is now fixed as of svn r1636.

Currently, constraints with an others() method don't work within a
Repeatable block - these are:
AllOrNone, DependOn, Equal, MinMaxFields, reCAPTCHA.
Also, the CallbackOnce constraint won't work within a Repeatable
block, as it wouldn't make much sense.

Note that increment_field_names(0) will cause $form->has_errors($name)
to not work as usual - it will only return true if all fields sharing
that name have no errors.
$form->valid() will also have wonky behaviour.

Cheers,
Carl
