Isochrones, area of the smaller distance not completely in the area of the larger distance?

Hello openrouteservice team,

why does the area of ​​the smaller distance lies not completely in the area of ​​the larger distance? For example, why is the yellow marked area in the area of ​​1 km, but no longer in the area of ​​3 km?

In fact, geometries calculated with code from the current main branch don’t exhibit the described phenomenon, see below,
