Pulsars shoot beams out of their magnetic poles so they are directed but in a beam. Even the narrowest would be lots of stars. They are also spinning so they sweep a larger area.
My guess, nothing is perfect, the rotation pole does not align exactly with the magnetic pole.
A second followup question, do stars tend to be coaxially aligned with their galaxy? it it possible to tell which way a star or pulsar is rotating?
Yes but this is a dynamic process that produces more correlated stars as the galaxy ages.
Astronomers routinely measure such parameters using models to provide confidence bounds for their estimates.
