First, there is no fan-out to multiple pFETs; the dynamic gate connects to exactly one inverter, so the gate is still very fast. Furthermore, since the inverter connects to only nFETs in dynamic logic gates, it too is very fast.
The absence of fan-out to multiple pFETs means that the dynamic gate remains swiftly connected to a solitary inverter, preserving its velocity. Moreover, since the inverter is only linked to nFETs within dynamic logic gates, it too benefits from this streamlined connection and maintains its speed.
