System Information
Operating system: Windows-10-10.0.17134 64 Bits
Graphics card: Intel(R) HD Graphics 630 Intel 4.5.0 - Build 26.20.100.7000

Blender Version
Broken: version: 2.82 (sub 1), branch: master, commit date: 2019-10-24 19:11, hash: 2a3b5dc730
Worked: (optional)

Short description of error
[it's not possible to snap several keys to the headplay(cursor) because space between them is not taken in consideration and they are simply merged. and this is not possible to have a list of selected keyframe to do it through an addon. so this lack could be considered as a bug or unfinished task]

Exact steps for others to reproduce the error
[Please describe the exact steps needed to reproduce the issue]
[Based on the default startup or an attached .blend file (as simple as possible)]

FCurve cleanup (keyframe merging) is not performed on snapping afaik, so technically these should still be separate keyframes.
FCurve cleanup is usually done when moving them by hand. (And only if the AutoMerge Keyframes option is ON)

So if this happens for you, please provide a simple .blend file

Or are you asking for a feature that the keyframes should remain their space between them for snapping?

yes keeping space between keyframes and another point to get a list of selected frames. because without this, this is difficult to put some functions in addons to work on several keyframes at once. someone did a little addon, using fcurves. this moving selected points (selected keyframes) and it keeps the space. but if you want to move several frames further that a next key, you are doing nodes in your curves. because this is not a cut just a move. watching the API you see there is no cutting function using Fcurves. but in dopesheet or timeline this is possible. but now the problem become the lack of possibility with selection.

how is it possible to open an animation branch?

This is intended behaviour, in the same way that snapping multiple objects to the 3D cursor will put them all at the same position. Blender currently doesn't have a snap-with-offset for keyframes.

Closing as 'invalid' as this is not a bug. We do have ideas to add something like this to Blender, but as I said, it's not a bug in the current implementation.
