NOTE - When dragging the BBT ruler, musical snap has no effect, however be warned that non-musical snap is in effect if enabled. Snapping to a minute while dragging a beat may result in some verly slow tempos. Snapping a beat to a video frame however is an incredibly useful way to ensure your soundtrack is punchy and synchronised to the sample.

you dragged the BBT ruler, making the second tempo provide enough pulses over the ramp for 4|1|0 to align with the desired frame.
If your ramp doesn't feel correct, you may add more points within it and keep adjusting beat positions in a similar manner.

Audio locked meters can be useful when composing, as they allow a continuous piece of music to be worked on in isolated segments, preventing the listening fatigue of a fixed form. Reassembly is left as an excercise for the reader.
