Broomstick Flyer:
I fly around the same airspace and this instruction at first I would understand "cleared to intercept the ILS final approach course and proceed on the approach"
The MSA in that area is FL65. If you maintain that until you intercept the ILS from the position described it seems you would be intercepting way too high. OTHO, if you disregard the MSA while offcourse, that seems to be what has caused more than a few CFITs over the years.
