A clause can never observe writes made by a later clause, and will observe all writes done by the previous clauses.

As of Cypher 25, read and write clauses can be combined in any order.
That is, a write clause followed by a read clause no longer requires a separating xref:clauses/with.adoc[`WITH`] clause in order for the read clause to observe the changes made by a preceding write clause.
For example, the following query, in which the changes made by a write clause (xref:clauses/set.adoc[`SET`]) are observed by a subsequent `MATCH` clause without an intermediate `WITH` clause, is valid using Cypher 25 but not link:https://neo4j.com/docs/cypher-manual/current/clauses/with/#combine-write-and-read-clauses[Cypher 5].
