Comment (by goldfire):

 Ah, yes, that makes some sense. When the pretty-printer appends `_xyz` to
 an identifier, that's the identifier's `Unique`. TH `Name`s sometimes lead
 to identifiers with `Unique`s (e.g., `newName` identifiers and identifiers
 from quoting) and sometimes not (`mkName`). In the latter case, the
 variable will refer to the innermost identifier with the same name,
 regardless of its `Unique`.

 I agree the pretty-printer is confusing here. Maybe instead of `x_a3uK`,
 it should be `x{a3uK}`? It would then be clear that the underscore isn't
 part of the name proper. Not sure if this is better or worse.
