Interplay between Dimensional Slide and Friendly Switch

RAW, am I correct in thinking that the Arcanist Exploit Dimensional Slide and the feat Friendly Switch would work together? For example, if I were to use a 5th level Arcanist (or Exploiter Wizard) could I teleport 50ft to the square another is character in, and then move them 50ft to the square I came from?

I can't see anything in the wording that would disallow it and the flavour would be me moving them through the portal I'd created. Seems like a good way to rescue someone or reposition a fighter as neither move would cause an AoO.

You could use it, but it wouldn't work the way you want it to.

Nothing in Dimensional Slide allows you to teleport allies through your portals. Friendly Switch requires the allies to be able to move to the square you came from, and if they can't teleport they can't do that.

However.

You COULD teleport to the square behind them, then continue your movement into their square, and they'd be shunted into the square behind you.

It's not nearly as powerful as what you were trying to do, but it's still useful sometimes.
