Artie - Like soooo many pilots, you missed the point. No controller says "LIne up after, etc". What he will say is "AFTER the landing/departing... line up".
Theory being that the first word the pilot hears is the condition "After". He doesn't hear "Line up" and start moving before hearing the conditional bit.
It's a safe, effective way of delivering an instruction in a potentially dangerous situation. If all pilots adopted the same R/T procedures as ATC a lot of incidents might be avoided.
