To summarize, we get the following constraints P_≥ for the following pairs.

280_0_MAIN_LOAD(x1, 0) → COND_280_0_MAIN_LOAD(>(x1, 0), x1, 0)
- (x1[0] ≥ 0 ⇒ (U^Increasing(COND_280_0_MAIN_LOAD(>(x1[0], 0), x1[0], 0)), ≥)∧[(2)bni_12 + (-1)Bound*bni_12] + [bni_12]x1[0] ≥ 0∧[(-1)bso_13] ≥ 0)
COND_280_0_MAIN_LOAD(TRUE, x1, 0) → 280_0_MAIN_LOAD(+(x1, -1), 0)
- ((U^Increasing(280_0_MAIN_LOAD(+(x1[1], -1), 0)), ≥)∧[bni_14] = 0∧0 = 0∧[1 + (-1)bso_15] ≥ 0)
280_0_MAIN_LOAD(x1, x0) → COND_280_0_MAIN_LOAD1(&&(&&(>(x1, -1), >(x0, 0)), <(0, +(x0, x1))), x1, x0)
- (x0[2] + x1[2] ≥ 0∧x1[2] ≥ 0∧x0[2] ≥ 0 ⇒ (U^Increasing(COND_280_0_MAIN_LOAD1(&&(&&(>(x1[2], -1), >(x0[2], 0)), <(0, +(x0[2], x1[2]))), x1[2], x0[2])), ≥)∧[(2)bni_16 + (-1)Bound*bni_16] + [bni_16]x0[2] + [bni_16]x1[2] ≥ 0∧[(-1)bso_17] ≥ 0)
COND_280_0_MAIN_LOAD1(TRUE, x1, x0) → 280_0_MAIN_LOAD(x1, +(x0, -1))
- ((U^Increasing(280_0_MAIN_LOAD(x1[3], +(x0[3], -1))), ≥)∧[bni_18] = 0∧0 = 0∧0 = 0∧[1 + (-1)bso_19] ≥ 0)

The constraints for P_> respective P_bound are constructed from P_≥ where we just replace every occurence of "t ≥ s" in P_≥ by "t > s" respective "t ≥ c". Here c stands for the fresh constant used for P_bound.
Using the following integer polynomial ordering the resulting constraints can be solved
Polynomial interpretation over integers[POLO]:

POL(TRUE) = 0
POL(FALSE) = 0
POL(280_0_MAIN_LOAD(x₁, x₂)) = [1] + x₂ + x₁
POL(0) = 0
POL(COND_280_0_MAIN_LOAD(x₁, x₂, x₃)) = [1] + x₂
POL(>(x₁, x₂)) = [-1]
POL(+(x₁, x₂)) = x₁ + x₂
POL(-1) = [-1]
POL(COND_280_0_MAIN_LOAD1(x₁, x₂, x₃)) = [1] + x₃ + x₂
POL(&&(x₁, x₂)) = [-1]
POL(<(x₁, x₂)) = [-1]

The following pairs are in P_>:

COND_280_0_MAIN_LOAD(TRUE, x1[1], 0) → 280_0_MAIN_LOAD(+(x1[1], -1), 0)
COND_280_0_MAIN_LOAD1(TRUE, x1[3], x0[3]) → 280_0_MAIN_LOAD(x1[3], +(x0[3], -1))

The following pairs are in P_bound:

280_0_MAIN_LOAD(x1[0], 0) → COND_280_0_MAIN_LOAD(>(x1[0], 0), x1[0], 0)
280_0_MAIN_LOAD(x1[2], x0[2]) → COND_280_0_MAIN_LOAD1(&&(&&(>(x1[2], -1), >(x0[2], 0)), <(0, +(x0[2], x1[2]))), x1[2], x0[2])

The following pairs are in P_≥:

280_0_MAIN_LOAD(x1[0], 0) → COND_280_0_MAIN_LOAD(>(x1[0], 0), x1[0], 0)
280_0_MAIN_LOAD(x1[2], x0[2]) → COND_280_0_MAIN_LOAD1(&&(&&(>(x1[2], -1), >(x0[2], 0)), <(0, +(x0[2], x1[2]))), x1[2], x0[2])
