5-5 ALS XZ at r2c13489 and r4c56,r5c4,r6c45, with X-value of 1 and Z-value of 2:

(2=1) r2c13489 - (1=2) r4c56,r5c4,r6c45 => r2c5 <> 2; lclste.

Alternatively; (2) r2c5 - r1c6 = (2-1) r5c6 = r5c4 - r2c4 = r2c5 => r2c5 <> 2

Written as 1r2c5=r789c5-r78c6=(1-2)r5c6=r1c6=>r2c5<>2, it is a Y Wing Style (! a sometimes not easy to find Type 7 !) or a Purple Cow (see n° 8).
OT, BTW, have a look here, if it may help !

More colorful Sudoku terminology.

I never saw a Purple Cow,
I never hope to see one;
But I can tell you, anyhow,
I'd rather see than be one.[1]

Ah, yes, I wrote the "Purple Cow"—
I'm Sorry, now, I wrote it;
But I can tell you Anyhow
I'll Kill you if you Quote it![2]

As to Y-Wing Style, I think that's very clumsy wording used as a noun. :lol:

But don't hold your breath waiting to find one in one of my solutions, as much as I'd like to. :cry:
