Why This Matters Across Episodes
The longer arc this connection carries
The Doctor explicitly tells Styles that the Daleks will return and the threat is not over. This sets Styles on a path to take a security role on a station that becomes a target, culminating in him being on the bridge during the final stand against Dalek fire.
