No, this is not the 2nd of 2 full moons for May, this is a different kind of Blue Moon.

May 2019 has a 'Seasonal Blue Moon.' If a season has 4 Full Moons, then the 3rd is traditionally called a Seasonal Blue Moon.

We had no idea there were two types of a Blue Moon, did you?

Here are definitions for 'Blue Moons' according to the Farmers Almanac.

Seasonal Blue Moon: The extra full Moon that occurs within a season. One season—winter, spring, fall, summer—typically has three full moons. If a season has four full moons, then the third full moon in the season may be called a Blue Moon.

  • Calendrical Blue Moon: The second full moon of a calendar month. It takes our Moon about 29.5 days to complete one cycle of phases (from new Moon to new Moon), so if a full Moon occurs on the first of a month, there will be a second full Moon at the end of the month, too (except in February).

No a Blue Moon is not actually blue, and we can't forget about the phrase 'once in a blue moon' which means rarely happens and is not taken literally.
