In this case however what I was thinking about that original comment wasn't if it is the right or wrong way (according to personal preference) but if indeed it is possible at all.
I'm thinking the technique might've worked for someone in a very specific and narrow range of conditions but wasn't thoroughly (if at all) tested in other places to validate. Perhaps it came to someone as a "Voila! moment" in a hypoxic state 2/3 of the way up one of those 5-mile zig-zag passes in the Sierras. ;^)
Very few things work the same for everyone everywhere!
