Quite right, Skyjob. I have very frequently had instructions just like that given to my while still decelerating through 100kts on landing. It's not just the complexity of the instructions but also their timing in giving them. Of course, anyone that has been there will also be familiar with the exact opposite style of taxy instruction of "follow the company ahead", no route, no limit, no clue! If the one ahead goes the wrong way, so will you! To be fair, the controllers don't show any sign of irritation or exasperation when I ask them for something more specific.
