I made a crude diagram for you

Note how it matches Feynmann's own analogy of antimatter:
>It is as though a bombardier flying low over a road suddenly sees three roads and it is only when two of them come together and disappear again that he realizes that he has simply passed over a long switchback in a single road

The diagram can be more complex, with multiple "creation" and "annihilation" events (resp. going in/out of FTL), all portions can be arbitrarily long and they don't have to be neatly observed at the same point in time
Generating all possible situations is trivial
What cannot change is that there has to be an emission and absorption point, and that it has to be the same electron through the whole path

Because QFT, due to relativity, is only allowed to speak about the second diagram, as it can't recognize the causal link identifying the two electrons and the positron, there's nothing to prevent you from thinking that there is only one electron in the universe, travelling forwards and backwards in time to "be" all positrons and electrons
Hence, the one electron universe


This also implies that beta+ decay is the capture of a high speed electron interpreted as the emission of a positron, that neutron decay is caused by collision with a high speed neutrino dislodging the proton and electron that compose it, interpreted as the emission of an antineutrino, etc for all emissions of "antimatter"
Also note that pair production can only happen near atomic nuclei. That is because the electron has to interact with something in order to slow down

Photons being their own antiparticle means that we cannot tell their direction of travel, so we infer it from the relations it had between the other particles. The difference is recovered in the "antiphotons" described in the paper I linked
I repeat that this only applies to high energy experiments, where we infer the paths and speeds of the particles through indirect means of backwards theoretical calculation
