Good question. Yesterday I asked the same to the S.A and it appeared is a strategy especailly the Koren / French designed also involved High Class Condo on it. which possible with high price once the rest of infra in place.
It make make sense for me. end of day they want high profile too and time line to complete are 5 years lol...
If look at HVO, where the may want to wait till HVO completed before start it.
