My take is the developer has a plan and an investor ready to spend now. The french side planning regs are not final, not sure he can get space on Orient and maybe found La Sand location not perfect.
So he is developing where he can now with the investment $'s ready to spend. If he waits,maybe he loses his investor?
I take this as a partial comment on the Fr side vs Dutch side current status of recovery as much as anything else.
