My understanding is that this (unsigned int) is intentional. The goal
is for only the low 32 bits of jiffies to overflow, even on 64 bit
architectures.

No. This was deliberate since testing 32 bit jiffies wrap seems more
beneficial than testing 64 bit jiffies.
Just the formulation might be misleading, which is why I initially wrote
#define INITIAL_JIFFIES (0xffffffffUL & (unsigned long)(-300*HZ))
