According to documentation, it does act on them, only later:

  Optional fourth argument CAN-RETURN-SWITCH-FRAME non-nil means that
  this function will process a switch-frame event if the user switches
  frames before typing anything.  If the user switches frames in the
  middle of a key sequence, or at the start of the sequence but
  CAN-RETURN-SWITCH-FRAME is nil, then the event will be put off until
  after the current key sequence.
