Jae-Won, My out of date Australian version of this spec requires the higher temperature glow wire for connections carrying more than 0.5 amp. You mentioned 0.5 mA so I may be on the wrong track.
I believe the concern here is a connection carrying more than 0.5 amp is more likely to obtain a higher temperature than a connection carrying less than 0.5 amp. It would make sense to do the test at a higher glow wire temperature when the terminal carries the greater current and is likely to get hotter.
