  A metric that describes a collapsing star and the surrounding black hole
geometry accounting for quantum gravity effects has been derived independently
by different research groups. There is consensus regarding this metric up until
the star reaches its minimum radius, but there is disagreement about what
happens past this event. The discrepancy stems from the appearance of a
discontinuity in the Hamiltonian evolution of the metric components in
Painlev\'e-Gullstrand coordinates. Here we show that the continuous geometry
that describes this phenomenon is represented by a discontinuous metric when
written in these coordinates. The discontinuity disappears by changing
coordinates. The discontinuity found in the Hamiltonian approach can therefore
be interpreted as a coordinate effect. The geometry continues regularly into an
expanding white hole phase, without the occurrence of a shock wave caused by a
physical discontinuity.
