Mystic Mindbreaker question

[VeratiaGames]

the mindbreaker connection for the mystic has this on its spells info.

Spells: 1st—6th mind thrust; replaced by 1st—lesser confusion,
2nd—inflict pain, 3rd—synaptic pulse, 4th—confusion, 5th—feeblemind

it says the the mind thrust is replaced by the other spells, does that mean its a player choice on whether to replace the mind thrust spells for those specific levels? or do you keep mind thrust, and still get the other spells?

[KingOfAnything]

You always have mind thrust as your highest level spell.

So at first level:
1st- mind thrust

When your mystic reaches level four, you gain 2nd level spells. So, mind thrust becomes a 2nd level spell, and your 1st level spell is replaced with lesser confusion

So at fourth level:
1st- lesser confusion
2nd- mind thrust

And so on,

So at tenth level:
1st- lesser confusion
2nd- inflict pain
3rd- synaptic pulse
4th- mind thrust

It mentions this in the Connection Spells class feature.

Starfinder Core Rulebook page 84 wrote:

If your connection lists a single variable-level spell (see page 330) for all spell levels at the start of its spells entry, you gain that variable-level spell when you first get your connection spell for each level. The next time you gain a connection spell, add the next higher level of the variable-level spell to your list of spells known. You immediately lose the lower-level version of that variable-level spell and replace it with the listed connection spell for that lower level.
