Yes, you are correct, except the Bb7 chord here replaces E7 going to A (or to D/A, the cadential 6/4 that is really an A chord with two suspensions. I imagine the next chord is D7/A, rather than D7 root position?). One of the problems with chord symbols is that they don't always reflect the exact harmony with perfect spellings. Tritone subs and diminished chords are often respelled as well.
While the proper chord symbol would be Bb7/Ab (or Bb/Ab) it would actually be better spelled out in the bass part as G#, to show proper leading tone function. I can almost guess the progression here. Is it D, D7/F#, G, Bb/Ab, D7/A ?
