Most likely its because the Philco uses line caps while the AK does not. Since one side of the AC line ( neutral ) is connected to the house ground at the eleclrical panel, the Philco chassis is effectively grounded at RF through the line cap on the neutral side.
As far as the AK, it has no line caps but instead uses a interwinding shield between the primary and secondary of the power transformer. So the circuitry is isolated from ground and the set really needs an external ground connection for proper operation.
