Question about lossy and lossless

Hi all, I have some troubles of understanding lossy and lossless video.

For ex:
I encode raw source A1 to B1 through lossy method.
Then when decoding B1 I have raw A2.

So B1 is lossy of A1 and B1 is lossless of A2, is it right?

If yes, then I encode A2 to B2 through lossless method, but It'll never touch the size of B1. I can not understand this.

Please help me, thank you guys
