So why would you come to that conclusion? Why wouldn't you cross after the 'aircraft' that had just touched down? Would all pilots react that way?
The clearance is confusing and therefore unsafe.
I would query the clerance.
If I was not happy then I would sit where I was - not breaking any rules and 100% safe. Pilots should remember that they are the ones that have the final decision (and responsibility) as to accepting a clearance and are entitled to refuse it and ask for a better (safer) one.
While they wait for the new one they can moan to the passengers about ATC delays!!
