Grey Goose
My original thought (which is usually the most accurate) regarding this, is that they were using bread as a visual aid as a type of subconscious reminder to not eat of the bread this year if you do not want to grieve, or even sin, against the holy spirit...Bit suspect they use a bread illustration the month before the memorial...
A subtle warning from the Governing Body that partaking of the bread and wine unworthily could incur the Second Death. A warning? The Seven should also be very afraid lest they suffer the same fate.
This demonstration appears to be disrespectful of the Memorial Celebration.
