50% duty cycle is not a must. With other duty cycles the maximum clock frequency of operation will be reduced.
Whether duty is 10% or 50%, the output data from a flop is available for entire cycle(minus Ck->Q) starting at the rising edge of the clock(if pos edge flops are in use), and this data is captured by the receiving flops at the rising edge. There is nothing where the neg edge clock comes into picture. As long as the same edge is used for all the flops, duty doesn't matter.
Minimum pulse width must be met though.
