Вторая ступень на Фалконах начинает работать после отсоединения первой, соответственно и посадка первой не зависит от циклограммы работы второй, сколь бы причудлива эта циклограмма не была.
Я выше привел ссылку, оттуда:

This required the second stage to enter orbit with a healthy amount of propellant still inside its tanks – a requirement that therefore drives the need to launch the mission on the Falcon Heavy instead of a regular Falcon 9 because the Falcon Heavy can provide the extra margin to the second stage whereas the regular Falcon 9 – even in its expendable configuration – could not.
Even with the Falcon Heavy’s performance, the center booster – given final mission and performance margin calculations and needs – had to burn so much of its fuel during first stage flight that it was incapable of performing a Boostback burn and therefore free-flew itself 1,200 km downrange from the launch pad before reigniting its engines for the Entry and Landing Burns.
This was to mark the farthest-ever downrange landing of a SpaceX rocket, with Of Course I Still Love You positioned ~1,245 km east of the launch pad. However, the booster – not unsurprisingly – missed the drone ship.
