Prismatic Burst mechanics contradict previous 3.15.0 patch note regarding Prismatic gem tag

In Version 3.15.0, the following patch note was listed:

"

Added a new “Prismatic” Gem Tag. This applies to skills which pick a random element to attack with, avoiding choosing the same element twice in a row. Elemental Hit and Wild Strike now have this tag.

However, Prismatic Burst Support lists that "Having higher strength makes it more likely to choose fire, higher dexterity makes it more likely to choose cold, and higher intelligence makes it more likely to choose lightning."

Does this mean that the restriction of not choosing an element twice is not inherently part of the Prismatic tag?

The tags are straight out ignored with the jewels.

The jewels has absolutely nothing to do with his question though.
That text is on the support gem itself.
