Once the RIPE NCC has to allocate addresses from the last /8, then from that point in time the distribution "will only be done as follows", which is specified in the "1. Allocations for LIRs from the last /8" and "2. Unforeseen circumstances" sections. The text is pretty clear that I think.

I am afraid the text of ripe-509 is very clear:

"The following policies come into effect as soon as RIPE NCC is required to make
  allocations from the final /8 it receives from the IANA.
  From then on the distribution of IPv4 address space will only be done as follows:"


This says two things:

1. These policies do not have to be applied as long as
the RIPE NCC has other available addresses than the last /8

2. Once these policies have been triggered, there is no way back
(see "From then on...").

The current policies do not allow this. You may want to submit a new
proposal.

I personally do not think it would be wise to allocate returned addresses
in accordance with policies applicable before the last /8, if we already
started to allocate from the last /8 (i.e. I do not think it would be wise
to have two sets of policies, both live at the same time, one applicable to
the last /8 and an other one to the returned address space).

For the record, I support the "Post-depletion IPv4 address recycling" policy.
