Yes, but the answer is not that simple. (you speak Dutch?)
If you are racing and you gotta change sails in a short while, nothing gotta be whipped or stitched (seized like on the vid.) as you must cut it when you are changing sails and you have to re-tie the sheets to the new clew.
Then, only tieing the bowline in and letting the wind work for you helps.
Presume, you are not using hawsers for a sheet like presently!
The whipping or seizing is a permanent fix and is done on cruisers with furling sails which don't get changed often.
One could apply simple whipping or french whipping where you don't need a needle instead of seizing, where you do it with a needle.

... whhooopsy, time for a hand stand...

The two above, are whippings and they can be done in minutes to tie the bitter end to the line, just think laterally!

This two are seizings or stichings with a needle applied. Takes a bit longer but much stronger, more permanent.
If one is desperate and hopelessly incapable of doing the above, a few inches of electrical tape will do splendidly. It gets mushy on the sun and spoils the line but it will do. No cable ties here, they cause more trouble.
As far as the racking seizing is concerned, l would rather tie a halyard knot and seize it. This way the braking strength of the knot would be 75% of the braking strength of the line while the seized only loop would be only 40% of the line's braking strength!
A consideration when one is doing this to a sail to be used in high winds, like a storm sail.
