No, here's my text again:

] LIR's may assign up to a /48 to an End Site.  End Sites requiring
] more address space than a /48 may be assigned a larger block provided
] the utilization inside that block meets an HD Ratio of 0.94.

The first sentence is clear.  Assign /128's, /112's, /64's, /56's,
or /48's to your customers.  No questions asked, ARIN does not
meddle in these assignments in any way shape or form.  The entire
space from /128-/48 is wide open and up to each individual ISP.

Only if you need to assign something larger, a /47-/1 do you then
need to meet an HD Ratio of 0.94 for those larger assignments only.
