Permission is only required if you plan to do a contribution that involves more than 3 pages (which was the case here), if the contribution was unnecesary undoing it on every page would take lot of work often.

In this case your edits were okay so there's no problem, but like cardboss said you should ask permission ONLY if necessary.
