The way I understand the LLHS-LSJC phrase is interaction between the opponent and yourself, how to act in relation to the opponent;
-When the opponent "advances" (loi) you "remain" (lau), i.e. make use of angling and such to keep the pressure forward but don't retreat taking pressure away.
-When the opponent "retreats" (heui) you "see them off" (sung), i.e. you advance keeping the pressure on them.
-When the opponent's "arm is removed" (lat-sau) you "rush straight" (jik-chung), i.e. you strike forward to their center.
LLHS is all about that constant forward energy.
LSJC is an effect of that energy when met with and once breaking obstruction.
I see you interpreting LSJC as LLHS, i.e. constant forward energy moving the whole structure as one unit. As a result, you replace LSJC with LLHS and deny the "springy energy" effect.
Well, what happens when contact is made with that sort of forward energy and is then suddenly lost, either by means of you removing the obstacle or the opponent taking their arm away? Do you not automatically "thrust forward without hesitation"? That is the LSJC part. If you aren't getting that effect, then something is wrong with your LLHS/forward energy. That's why it appears first in the phrase.
