Notes
Related patterns
Similar
てから welds the two events tightly (often a precondition) and alone carries the durative "since" reading (来てから三年になる); たあとで merely states the order and tolerates any gap.
Lookalikes
The same から splits on what precedes it — after the て-form it orders events (飲んでから帰る "go home after drinking"), after a finite clause it gives a reason (飲んだから帰る "going home because I drank"); learners routinely misparse one boundary as the other.
