- * transition makes it to the head of the "ready" queue, it will attempt to merge to with the
- * "active" transition. If the merge succeeds, it will be moved to the "active" transition's
- * "merged" and then the next "ready" transition can attempt to merge.
+ * The READY and beyond lifecycle is managed per "track". Within a track, all the animations are
+ * serialized as described; however, multiple tracks can play simultaneously. This implies that,
+ * within a track, only one transition can be animating ("active") at a time.
  *
- * Once the "active" transition animation is finished, it will be removed from the "active" list
- * and then the next "ready" transition can play.
+ * While a transition is animating in a track, transitions dispatched to the track will be queued
+ * in the "ready" state for their turn. At the same time, whenever a transition makes it to the
+ * head of the "ready" queue, it will attempt to merge to with the "active" transition. If the
+ * merge succeeds, it will be moved to the "active" transition's "merged" list and then the next
+ * "ready" transition can attempt to merge. Once the "active" transition animation is finished,
+ * the next "ready" transition can play.
+ *
+ * Track assignments are expected to be provided by WMCore and this generally tries to maintain
+ * the same assignments. If, however, WMCore decides that a transition conflicts with >1 active
+ * track, it will be marked as SYNC. This means that all currently active tracks must be flushed
+ * before the SYNC transition can play.
