P1 vs. P2 seat post

It appears the P1 does not have the extra forward position option that the seat mast of the P2/3/4 has…is this correct?

Also, are there any other aluminum Cervelo’s other than the P1 and P3SL?

you can flip the head of the seat post head around for a more forward option on the p2sl (p1), dual, and p3 alu
