Question on RNAV RWY 18

Question on RNAV RWY 18 as depicted at Crash: UPS A306 at Birmingham on Aug 14th 2013, touched down outside airport
The point ‘BIDPE’ is additional to those shown on the LOC procedure. What is the purpose of this point other than for terrain clearance at that range?
Is does not appear to be part of the 3.25 deg GS path, and could be misinterpreted as a check altitude (2600ft) – 2000ft AAL, but at 8.7 nm this would be well below the anticipated approach path.
The procedure altitude check appears to be at the FAF ‘BASKN’; there is no altitude-range table to help monitor the approach. Without additional safety aids would the crew rely totally on the RNAV glidepath, and thus depend on the correct interpretation / programming of the procedure – including altimeter pressure setting?
Procedure NA without VGSI ? (PAPI OTS, #60)
