I would say you are right! A very good photo. Bob from previous post you have mentioned several times that you are using long hives. If so the following may not be helpful in answering your question. In a regular Langstroth hive, bees will move honey up IF they have been deprived of available storage space in which they were forced to store excess honey in the brood area. When supers are (made available), ie. bees will move honey up. This might however be to late as far as swarm mode is concerned. As you know a lack of brood space will kick in swarm mode during a flow. For curiously, is the honey being uncapped in the brood area?
ie.
Sometimes space was provided in a proper time frame by added supers but their use, can be restricted by the unskilled use of Queen excluders.
