What does "after" mean and "is set"?  At a later point in the source
text, at a later time in musical execution?

With regard to the latter (which you could access in callbacks or
\applyContext) \tempo sets the context variable tempoWholesPerMinute in
the Score context.  How this relates to X and Y depends on the unit of
the beat.  A reasonable guess is it is measured in baseMoment beats,
possibly multipled by the gcd of the values in beatStructure (if any).
At least that's what Time_signature_performer tries to state.
