"it will not be counted in the number of the allowed jumps of the concerned jump combination" does read to me like they would only say two jumps happened in 3A+1Eu+3S, but I guess we'll wait for examples.
But this is what I was happy about, that we could get back combos like 3A+2T+2Lo instead (hopefully they won't default to ugly +2A+2A sequences... hoping for a fix to that, no need to see sequences being allowed for 3 jumps), since otherwise the three jump will go empty. And with the change, 3A+1Eu+3S (12.80 -> 12.30) loses its appeal ranking behind 3A+3Lo (12.90) which looks far prettier, or it will force someone to use their Flip in combo like in 3A+1Eu+3F (13.80 -> 13.30) and hopefully shake the rest of the layout up and make extra points up elsewhere.
