Narrative:

We were training on ground control. We had aircraft X on taxiway G holding short of runway 6. Aircraft Z was on taxiway G holding short of taxiway left. Aircraft Y was flaring out to land rwy 6. The trainee told aircraft X to follow a gulfstream and continue via left. However this instruction was meant for aircraft Z. Aircraft X never moved then stated he was told to cross the runway with an aircraft flaring out. The 'cross' instruction was never issued. No runway incursion took place but an accidental; ambiguous instruction was given to the aircraft which could be misinterpreted as a runway crossing.we believe this mistake took place because the trainee was using a confusing strip posting technique. We reviewed better ways to make strip postings less confusing and more efficient.

Title: TEB Instructor reports of a situation where an aircraft thought they had clearance to cross a runway but did not due to an aircraft flaring out on the runway. No incursion occurred and the pilot did not move the taxiing aircraft until later.

Narrative: We were training on Ground control. We had Aircraft X on taxiway G holding short of runway 6. Aircraft Z was on taxiway G holding short of taxiway L. Aircraft Y was flaring out to land Rwy 6. The trainee told Aircraft X to follow a Gulfstream and continue via L. However this instruction was meant for Aircraft Z. Aircraft X never moved then stated he was told to cross the runway with an aircraft flaring out. The 'cross' instruction was never issued.
