On the matter of
O'neal UK Limited
to be considered the 'same as'
1 ALS LIMITED
This is because the algorithm used to check removes all words like 'UK', 'limited', and punctuation, then turns '1' into 'one' and also ignores any plurals. This makes them both look like ONEAL, thus are considered same as.
You can still attempt to incorporate companies that show as 'same as' but your submission will be examined using a more complex algorithm, and if (like this one) is clearly not the same, it will be allowed as a name.
Hope this helps.
