I think it's more likely that whoever put the tweet out for the agency just didn't know what an X-10 contract was and meant a summer-league deal. SL contracts are completely separate from regular deals. The Spurs signing Minix to play for their SL had nothing to do with him getting an X-10 deal now. Just to clarify, an X-10 deal is a one-year non-guaranteed deal that gives the team the option to convert it to a two-way deal automatically, as well as the X-9 provision allowing them to release the player and give their d-league affiliate the player's rights. I don't believe Minix had this, and I wonder why
timvp suggests he did given the SL grades posts he made about Minix's chances of getting a two-way contract and don't mention that he's already signed to the regular roster. If Minix was already on an X-10 deal, the proof was going to come from training camp, not the summer league.
Right now the roster looks like this:
Paul, Jones, Wesley
Vassell, Castle, Branham
Barnes, Johnson, Champangie, Minix
Sochan, Mamukelashvili, Cissoko
Wembanyama, Collins, Bassey

Two 16 full roster spots and one two-way with Ingram expected to sign some kind of contract. That 17/21 training camp spots taken with one spot expected to be filled. The Spurs have the room to sign three (technically four) players to X-10 or X-9 deals to fill up their roster. I think they get four X-9 slots a year, so we'll likely see them sign and cut some players either ahead or into camp. Whether Ingram is going to sign a two-way or an X-10 deal is to be decided, but for TC-slot purposes that doesn't matter.
