Question about edges

[Tim Gould]

I think my question is: do I care??? :-)

That is, at this point am I done snapping and I go home, or do I then need to re-run a snap to detect that 2 and E are close and merge them?

Is the above pattern a legitimate authoring technique or 'too much detail in too small of a place'?

Probably you do not care. If that situation comes up it's very likely to be a result of bad part design. Any detail finer than (say) 1/100th of an LDU is just plain wrong and setting TOL=1e-2 is likely to catch all but the most extreme rounding errors. The one notable exception is if a part used a rotation on something really long to match with another detail. Which is unreliable design and best caught at the design/review stage.

You could get rid of the problem by iterating until no matches are found. But that seems like overkill to me and is possibly more likely to result in false joins.
