Not quite.

In the "first timeline" (that we know of anyway) - F-Lucy's timeline - the Gate was opened in accordance with Eclipse Plan 1 (i.e. send someone back 400 years to kill Zeref), but the Gate went out of controll and allowed the 10.000 Dragons to invade. F-Rogue wasn't involved.

Lucy somehow survived and went back in time to prevent this catastrophe from happening. And she succeeded and thus created the 2nd one.

In the "second timeline" - F-Rogue's timeline - Lucy had somehow managed to close the Gate (or prevent it from being opened) and thus prevented the Dragon Invasion. One year later Frosch died and at some unknown point Acnologia decimated mankind. F-Rogue researched Dragon Manipulation Magic (or whatever the new name is) and set out into the past creating a 3rd timeline.

This "third timeline" is what we saw as the present timeline.
