The following scan is from Quarks and Leptons: An Introductory Course in Modern Particle Physics, Francis Halzen (Author), Alan D. Martin (Author), page 9. Can I take anything from the topological difference between figure (b) and (c)?
Thanks for any help!

Diagram (c) is not a Feynman diagram, just a way of illustrating the fact that color is exactly conserved. You can follow a continuous path that traces the B color, in one line and out the other. A gluon carries color and anticolor, so the two lines in the middle of the diagram both belong to the same gluon.

Referring to the scan above, does there exist a new diagram that could have been included in the book "Quarks and Leptons", call it figure (e), such that,
Figure (b) is to figure (c) as figure (a) is to figure (e)? See figure (e) below. If so can we think that the photon is equal opposite currents that cancel perfectly or nearly perfectly? Thanks for any help!
