Currently when $all criteria are combined the parameters are unioned, such that the combination is effectively an OR of the pieces rather than an AND:
irb(main):007:0> Band.all(foo:[2]).all(foo:[1])
=> #<Mongoid::Criteria
selector: {"foo"=>{"$all"=>[2, 1]}}
options: {}
class: Band
embedded: false>
Because of this, all can alter the meaning of existing conditions in the criteria. In the below example where is changed to be respected only some of the time:
irb(main):016:0> Band.where(foo:3).all(foo:[2])
=> #<Mongoid::Criteria
selector: {"foo"=>{"$all"=>[3, 2]}}
options: {}
class: Band
embedded: false>
Similarly to 4697, both conditions should be added as $all requirements (and the resulting query would be unsatisfiable in these examples).
