Total Noob Target Question (even though I'm not a noob and should know better)

If I don't fully fund a target but don't end up spending the money from that envelope, does rolling into the next month while it is still yellow mess me up?

What actually happened: January and February are fully funded. I was at the store and bedding was on super duper sale and I've needed new sheets for ages so I bought some. I was going to have an extra $60 in my transportation fund that would have rolled over into February, so I moved it to Groceries and Household.

Groceries and Household is green and happy and has enough to cover the sheets, transportation is yellow because it is technically underfunded, but it's fine because I won't need the money there anyway.

That's exactly how it is supposed to work, right? Everything is reconciled but I don't want to realize that it messed me up somewhere down the road.
