I could have sworn I read somewhere that there was a rule preventing from playing an all-holo playset of cards that come in holo and nonholo variants for this reason, but I can't find it any more, so I must have been imagining it or something...
That being said, I both agree and disagree with the previous two posters. Holos and FA cards have two points about them which can influence how the shuffling goes. For one, while it isn't very noticeable (especially with sleeves on), is that Holo/FA cards are *slightly* thicker, due to having a layer of foil and/or FA texture. It might not seem like much, but it can have a minor impact on the results of a shuffle.
Another factor is that Holo/FA cards tend to curve due to an effect of the thin sheet of foil returning to the shape that it was on the spool of foil before being applied to the card. This has an effect in shuffling on almost every shuffling method, and can also have a psychological effect when you have your opponent split- they might feel that a certain card feels slightly different, and then split the deck there. Also, if you shuffle by splitting the deck every few cards, a curved card will have less friction due to there being less surface area on the card above/beneath it, so it'll slide a little easier. Curved cards might also group together because they 'fit' into eachother, as opposed to perfectly flat cards sliding off one another.
Those being said, the above two posters are right- by mixing up the way you shuffle your deck and being super thorough about it, you should be able to avoid all your Leles being in the same spot in the middle of your deck
