I must say I've never eaten genuine lovage fruit (it's a fruit not a seed) but one thing is certain, lovage and ajwain are from different plants and they are not interchangeable. If your "lovage" smells and tastes like thyme then it is in fact ajwain. The genuine lovage fruit apparently gets mixed in and sold as celery seed so that's the flavour I would expect it to have. You have to wonder if the author of the recipe was actually using ajowain and not lovage, as the genuine lovage fruit(seed) is hard to obtain.
It's not helped by the major spice manufacturers labelling it incorrectly: http://www.spicesofindia.co.uk/acatalog/Indian-Food-TRS-Lovage-Seeds-Ajwain.html
