NO. this is wrong.

The limit screws are exactly what their name implies. They set the extreme inside and outside limits to the derailleur range. Think of them as the concrete barriers along the sides of a bridge so you can't drive too far to the side and into the drink. Te barriers determine the road width, but you have to choose and drive in the lanes.

The derailleur's mechanism hangs from the cable, and that determines it's position.

However, in practice there's an exception. Most derailleurs (both front and rear) are designed so the cable is overly slack in the slackest position (high in rear, low in front) and the derailleur is allowed to rest on the corresponding limit. So, the inside FD limit does affect the trim in low, but that's the only gear where it's used for trim.
