The paladin and swordmage would benefit greatly by having the bard apply their full mark on them form a distance. The fighter and warden not so much. This meshes with the OPs interpretation. Also, both paladins and swordmages have a limit on their number of marks, even if this limit is not expressed as a limit but as a limitation on how they use their marking power. It becomes quite complicated if the bard can add to these marks; you need to keep track of which mark is the bard's and which is the paladin's/Swordmage's. All of this is in favor of the OPs argument.
Still, I do not agree with the OP. I think there needs to be ONE way for Misdirected Mark to work - its workings cannot require this much text analysis. And my reading is that it does indeed activate all marking abilities. This is not from reading the fine print, but from my feeling of what the bard does; it plays on the abilities of his comrades, bringing out the best in each. Another example of this is Forceful Conduit. But this is an opinion, not something I want to present as fact.
I think the text is unclear in the extreme, but whichever way it goes, and I don't think we'll get clarity until we get an official reply, if then.
