Scene size keeps getting bigger with every saved version

Hello,

It's not really a problem, more a bit of confusion on my side...

I'm working on an animatic for an animation. The scene is set up of three objects that are referenced into a clean file. The set piece and two character-placeholders (basically unrigged low-poly objects).

The original scene has 560 kbyte when saved. Makes sense...

Every time I save this scene under a new name, the size of the file goes up. I'm on scene version 28 now and the file size has gone up to a 100 MByte over the past couple of days.
All I'm doing is importing an audio file, set a couple of keyframes for the position of the camera and characters, playblast and save under a new name when happy with it.
Afterwards I delete all keyframes and the audio files (which again are only a few kbytes in size, so even if left in the scene shouldn't go up to 100 MB anyway) and save the scene under a new name. 

Optimize Scene Size does nothing.

Like I said, it's not an issue at the moment, i'm just wondering what's going on...

Anyone got any idea? I'm on 2018 btw. Thanks
