Why are callbacks bound to LSequence invoked every frame?

 var handle = LSequence.Create()
    .Append(LMotion.Create(0, 1, 0.01f).Bind(x => Debug.Log($"[{Time.frameCount}] 1st: " + x)))
    .Append(LMotion.Create(10, 11, 0.01f).Bind(x => Debug.Log($"[{Time.frameCount}] 2nd: " + x)))
    .Append(LMotion.Create(100, 110, 0.01f).Bind(x => Debug.Log($"[{Time.frameCount}] 3rd: " + x)))
    .Run();
// outputs
[1] 1st: 0
[1] 2nd: 10
[1] 3rd: 100
[1] 3rd: 100
[1] 2nd: 10
[1] 1st: 0
[2] 3rd: 100
[2] 1st: 1
[2] 2nd: 11
[3] 1st: 1
[3] 2nd: 11
[3] 3rd: 110

Does this mean the start and end values are updated every frame to keep things consistent while the LSequence is running? So it’s not great for heavy processing, right?

Expected:

[1] 1st: 0      // maybe caused immediatebind
[1] 2nd: 10     // maybe caused immediatebind
[1] 3rd: 100    // maybe caused immediatebind
[1] 3rd: 100    // ?
[1] 2nd: 10     // ?
[1] 1st: 0      // sure
[2] 3rd: 100    // ?
[2] 1st: 1      // ok
[2] 2nd: 11     // ok
[3] 1st: 1      // ?
[3] 2nd: 11     // ?
[3] 3rd: 110    // sure
