That segment of an instrument approach procedure between either the intermediate approach fix and the final approach fix or point, or between the end of a reversal, race track, or dead reckoning track procedure and the final approach fix or point, as appropriate (ICAO). This is the segment during which the aircraft speed and configuration should be adjusted to prepare the aircraft for final approach. For this reason, the descent gradient is kept as low as possible. During the intermediate approach, the obstacle clearance requirement reduces from 1000 ft (300 m) to 500 ft (150 m) in the primary area, reducing laterally to zero at the outer edge of the secondary area. Where a final approach fix is available, the intermediate approach segment begins when the aircraft is on the inbound track of the procedure turn, base turn, or final inbound leg of the racetrack procedure. Where no final approach fix is specified, the inbound track is the final approach segment.

Procedure turn inbound" should be reported, when requested, when the course reversal has been completed and the aircraft is established inbound on the intermediate approach segment or final approach course.
They both have the same basic definition: A maneuver prescribed when it is necessary to reverse direction to establish an aircraft on the intermediate approach segment or final approach course.
In this case, with no intermediate approach segment, once you're established inbound within 10 miles of HLN, you are inside the "final approach point"--there's no FAF--and you can descend to the MDA of 6700 feet MSL.
The 1900-foot crossing restriction at the VOR is actually for an obstacle on the intermediate approach segment to the VOR.
The TERPS ROC for the intermediate approach segment is 500 feet within one mile of the aprroach-course center line.
