Morphology
The meaning 'to act or function in perfect harmony or unison' is directly derivable from combining 'beat' (a rhythm or pulsing action) with 'as one' (like a single unit). This is a compositional, imageable meaning (to share the same beat) that follows common cross‑linguistic patterns, so a B1 learner who knows the constituents would likely understand it.
Etymology
Beat as one may come from music or the image of many hearts or drums keeping the same rhythm. When every beat matches the one rhythm, the group moves 'in unison', so the phrase means 'to act in perfect harmony'.
