The holding pattern in lieu of a procedure turn is a way of getting you down from an altitude which is too high to leave the final approach fix inbound, while keeping you away from higher terrain near the edges of the 10-mile radius area around the final approach fix. You can fly the inbound leg while descending on the glide slope, and hopefully you will remember to check the altitude at which you cross the fix to make sure you're not below the altitude shown on the approach chart.
Call it what you will, a holding pattern in lieu of a procedure turn replaces the 45-degree, teardrop, 90/270, or whatever other procedure turns you can come up with.

Now you're really confusing me. Where did a glide-slope come from ? That, by definition takes care of altitude.
The MSA will take care of your altitude inside of 10nm.. Then, if you
choose (key word).. to put yourself in a position to need to use the hold for losing altitude, it's your call.. not required.
If you need to use the hold for course-reversal, you have to abide by standard hold rules, which pretty much amounts to a course reversal, at your discretion, so long as you stay in the protected area.
I'm not trying to be nit-picky.. just referencing the original poster's question about if he HAD to fly the hold.
