Can you explain "queued" in its description?

Can you explain where "queued" can be used for? Or what it blocks in combination with the option "loop", if it does(?)

Here's the new description:

queued
Type: boolean or string
Default: false
descriptions: define queued transition.
false: transition will happen simultaneously for X and Y axis
"x": will animate on the X axis, then on the Y
"y": will animate on the Y axis, then on the X
example: queued: 'x'
