Sorry, I don't see what you mean. 1) what do you call "tied notes after triplets"? Is it a note tied with the last note of the triplet or something else? 2) if the tied notes are after the triplet, it seems natural that they are played after, so probably what you mean is not what I understand from what you say
I believe that what is meant is that the tied note is treated as a separate note, having its own attack.
The Universal Principle of any problem involving a tie (as here, for example) is to un-tie it and replace it with a slur. (Sometimes you will find you cannot un-tie two notes and have to delete and re-write them).
