When using underscores for emphasis, MD037 is triggered when two strings with underscore characters emphasized with an underscore occur in the same paragraph.

The rule does not trigger errors when they occur in different paragraphs.

Here's an MRE demonstrating the issue

Passes:

Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor
incididunt ut labore _abc_123_abc_baby_u_n_me_.

Ut enim ad minim veniam, quis
nostrud exercitation ullamco laboris nisi ut aliquip ex _do_re_mi_.

Fails:

Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor
incididunt ut labore _abc_123_abc_baby_u_n_me_. Ut enim ad minim veniam, quis
nostrud exercitation ullamco laboris nisi ut aliquip ex _do_re_mi_.

In the document in question, I switched from using underscores for emphasis to backticks, since they are representative of encoded strings, but thought I'd note the issue anyway.
