I am reading the magazine, The Economist, July 3rd 2021, and there is a paragraph that I cannot understand. The paragraph is about the discovery of Guam, an island in what is now known as the Micronesia region of the western Pacific Ocean.

In 1686 William Dampier, an English pirate with an unlikely literary flair and a appetite for scientific and human observation, anchored the Cygnet off the coast of Guam, an island in what is now known as the Micronesia region of the Western Pacific Ocean.
...
Dampler's voyage came roughly midway between the European discovery of Guam, 500 years ago this year, by Ferdinand Magellan, during the Portuguese explorer's circumnavigation of the world, and the extraordinary Pacific voyages of Captain James Cook between 1768 and 1780. Magellan's stumbling upon Guam as a trans-ocean way-station between continents in effect launched the global age.

The Magellan expedition was the first voyage around the world. It was a 16th-century Spanish expedition planned and led by Portuguese explorer Ferdinand Magellan to the Moluccas, which departed from Spain in 1519, and completed in 1522 by Spanish navigator Juan Sebastián Elcano after Magellan's death, crossing the Atlantic, Pacific, and Indian oceans, culminating in the first circumnavigation of the world.[1] In 1686, when William Dampier docked in Guam, Magellan had finished his world tour.

What is the meaning of " Dampler's voyage came roughly midway between the European discovery of Guam, 500 years ago this year, by Ferdinand Magellan, during the Portuguese explorer's circumnavigation of the world" ? Is this sentence wrong?

Thanks in advance.

Dampier's voyage occurred halfway between Magellan's voyage and Cook's voyages.

The sentence places Dampier's voyage on a time line.
