This is a variant of this old issue:

https://gitlab.com/lilypond/lilypond/-/issues/923

Basically, the problem is that trill spanner must be printed with an
integer number of squiggles. Depending on the exact length of the
first trill, its last squiggle may, or may not, overlap with the
next trill, forcing the next trill to avoid it vertically.

You can circumvent the problem with

\version "2.22.1"

{
  d'2\tweak bound-details.right.padding 2 \startTrillSpan
  b2\startTrillSpan
  b1\stopTrillSpan
}


Best,
