Vds voltage arises from the circuit, it's not an inherent feature of transistor type.
 

The question has no sense..Did you mean Vds(max) ?
 

Not convinced this is true on any basis, let alone there
being a "why".

In my experience across numerous technologies, the P
device for equal reliability and equal L has a higher max
Vds. PMOS leakage "walks out" while NMOS "walks in"
from hot carrier type effects (which are usually the
limiter for Vds rating at short channel).
