Despite a long post the answer is short.
A second water based sealer, in my opinion, would be sufficient.
The first coat penetrates but as the tile is made from natural materials it probably won't be even, some tiles will take more seal than others. A second coat will make it look even.
Get a short pile roller and a dip tray which will make coverage even.
Next, if the old and new tiles are the same size and are going into the same area, mix them all up to get a random pattern rather than have part one shade and anther part a different shade.
Re your maintenance comment. It's a floor, it will need maintenance. It's the most used surface in the house.

Thanks Taranis - yes, apologies for the long post but thought it worth setting the context.
Interesting suggestion - I'd read that the waterproof sealant didn't leave the cotto impermeable or resistant to oils in particular - and since we use a lot of olive oil in the kitchen, this could be an issue. Do you think its wise to wax or use a resin finish in the kitchen for instance? In the bedrooms etc its probably less of a risk of course (although I do take the point about cosmetics sometimes).
Does the water based sealer leave any kind of finish - i.e., a shiny or matt finish - or does it leave the cotto looking as it does 'out of the box'?
Thanks again for your helpful reply!

The more seal you put on the shinier it will look. Once you have the correct amount it should have a silk finish, make sure you give it time to dry before making the choice on next coat or not. Best bet is to put tight coats on till you achieve the look you want. I can't say how the seals you've spoken about will look as I have never used them. I would go for a water based polyurethane.
Don't worry about doing it yourself, the seal will be easy to use. Start in a corner or a cupboard First so you get used to it. When done it should resist oil spillages.
Lastly, if you use a wax at any time every subsequent coat will need to be wax. No seal will stick to wax.
