For a more general case:
import torch
def same_storage(x, y):
    return x.storage().data_ptr() == y.storage().data_ptr()

# It works on your test.
t = torch.rand((3,3))
t1 = t[0,:]
t2 = t[:,0]

print(same_storage(t1, t2)) # prints True
 
x = torch.arange(10)
y = x[1::2]
print(same_storage(x, y)) # prints True
z = y.clone()
print(same_storage(x, z)) # prints False
print(same_storage(y, z)) # prints False
