The Release triggers into action ALL the Power Accumulators employed. If you are using, per 10-4, a Single Barrel (#2 alone) or Double Barrel Accumulator Combination (#2 and #3) then Release would occur as you describe. Both being low power strokes.
However, I don't believe I have answered your question in the context you mean it. As you refering to Release Motions in 4-D-0 and the Sequenced Release of the Swinger or the normally employed Swinger's Three Barrel (4-2-3) Total Motion Stroke Pattern (in which case the Release of #4 would precede #2)?
I took a quick look at the yellow book before I wrote my post and saw the
4-D-0 that you mentioned and this is where I came up with the Release beginning when #2 starts to release.
BUT what I am really after, in case your answer is different would be for a 4,2,3 Three Barrel swing. The question for this is "When should the right forearm begin to be on-plane" ?
