Yes.

Going from 2% -> 90% first requires you to go from 2% -> 60% both in the mathematical sense (2->60->90) and in the process sense (it's a lot less work to from 60% -> 90% than it is from 2% -> 90%) and also in the sense that you to first develop the technology to enrich uranium to various levels, then develop the technology to enrich it to that level at scale, enriching to 2% isn't that hard, enriching to 60% is hard, enriching to 90% is harder but the leap from 2->60 is a lot harder than the leap from 60->90.

In short, no, I don't think there is any practical reason to enrich to 60% unless your intention is to either enrich to weapons grade or as a threat to do so.
