So the 1M initial extent allocation is not due to a "5 block minimum allocation rule" but due to the fact that automatic space management requires 3 blocks plus 1 block for the segment header plus 1 block for actual data = 5 blocks, which lifts the request above the 64K threshold for a tablespace with 16K extents.
The "which lifts the request above the 64K threshold for a tablespace with 16K extents" is poorly worded. What I meant to say is "For a tablespace with a 16K block size those 5 blocks come to 80K which is more than the 64K first tier for autoallocated extents and you thus get 1 extent of the next tier size: 1M"
