My suggestion is to see whether there are the recoil effects and carry on with another technique like a grab and pull after a high intensity strike.

if we do that because of some heavy person pushing us, we "receive" this "force" using "eccentric contraction". we could redirect it from there. you do this in any grappling sport.

there's nothing there regards eccentric strength (thought there might be..). it's easier to conceptualise against resistance - bodyweight and gravity and or an external weight, object, force etc. for example lowering yourself from a chin up or pull up position is eccentric. or can be posited as an example of 'eccentric strength'..
An eccentric (lengthening) muscle contraction occurs when a force applied to the muscle exceeds the momentary force produced by the muscle itself, resulting in the forced lengthening of the muscle-tendon system while contracting (Lindstedt et al., 2001). During this process, the muscle absorbs energy developed by an external load, explaining why eccentric action is also called “negative work” as opposed to concentric (shortening) contraction or “positive work” (Abbott et al., 1952). Although not always obvious, eccentric muscle contractions are an integral part of most movements during daily or sport activities. Skeletal muscles contract eccentrically to support the weight of the body against gravity and to absorb shock or to store elastic recoil energy in preparation for concentric (or accelerating) contractions

imagine that portion of the exercise and ask yourself what does that have to do with that method of striking ?
personally I would say nothing, nothing at all really.
it's the same relationship that a push up (and its negatives) have with a punch, or as much as a squat has to do with a kick. It's a non specific physical training, other than plane of motion and muscle groups engaged
pulling on the resistance band - say horizontally toward you (stretching it) would actually be concentric and the way back (controlled) would be eccentric.
compare that to bend the bow shoot the arrow mechanics, how similar does that feel to you?
You want less muscle contraction, but you are training an exercise that's about muscle contraction against resistance to improve that.
Personally that's not the way i would look at it! It's basically an error of confusing motor control (and mobility) with strength
the elastic band principle of muscle activation ?
absolutely, but the activation will not be localised or simply 'eccentric' - it will be both.

Theoretical debate and hypothetical conjecture is always less valuable and less informative than validation through experiential learning derived from consistent daily assessment of feeling the internal and external aspects of actual training and application, imo. As always, ymmv.
