It's no illusion, it's the definition, and senders know that it can't
work reliably (if at all) if SPF is checked behind the border-MX.

As I understand it:

receivers that do SPF checks past the border are broken.  Repair
options include (1) special-casing border machines (2) doing SRS
forwarding from the border instead of plain forwarding.

Given the SPF point of view, non-SRS forwarding is broken and
should be replaced with SRS forwarding.  That is part of the
SPF adoption block.
