To first order, circuit is same. Shunt capacitance, from choke winding to core will have a reduced effect if the choke is in the ground end of the series circuit, giving a more gradual high frequency roll-off (resistor likely has negligible capacitance to ground). Possibly not a measurable effect within the audio frequency range.
Follow Ups:
I agree. The shunt capacitance of the choke winding to a grounded core (and possible shield) may have a measurable effect at high frequency. Assuming that this is an anode load to Vbb, the "grounded" side is actually the side connected to the plate supply voltage Vbb.
