The majority of the wake would end as soon as the main gear hits the ground. The aircraft will still create some wake until shortly after the front gear is on the ground. The small about of wake created after the main gear is on the ground is not relevant as it would be far less than the turbulent air that a 140,000 lb 737 rolling down the runway shortly after landing would create.

It’s been almost 3yrs since I worked intersecting runways operations but if I remember right, wake turbulence is not relevant in this situation. If you have a twin cessna in position and a 737 lands on the intersecting runway and crosses the intersection the cessna can begin departure roll. Again it’s been a while since I had this situation.
