*NO*. In general, an overloaded resistor typically burns up, may blow off its coating, or even fracture its body if the overload was severe enough, or if ceramic or metal cased may spew its guts out one end. I cant think of any failure mode without exposure to harsh chemicals that could cause one end to selectively swell.
For a vitrified wire wound resistor like that one, that is effectively hermetically sealed inside an inflexible vitrified ceramic coating, even harsh chemicals couldn't do it. Its almost certainly due to original uneven coating, or its orientation while the coating was fired to vitrify it.
Measure its resistance - if its still 22 ohms +/-5% its still good.
