Unexpected behaviour with skill practice

When we start a practice session from a skill page we are taken to a practice page for that skill (eg. http://duolingo.com/#/skill/fr/Prepositions/practice). At the end of a practice session if we click the "Practice again" button we are taken to be the general practice page (http://duolingo.com/#/practice/timed), not the skill specific practice page that we started from. It seems more intuitive to me to return to the skill practice page, not the general practice page, but perhaps I have misunderstood. Has anyone else noticed this?
