MapMatching and Direction API disagree

Hi all,

I'm using Mapbox Navigation SDK (mapbox-android-sdk:8.6.0-alpha.2, mapbox-android-navigation:0.43.0-alpha.1) to navigate along an pedestrian itinerary set by waypoints that my server computed.

To do so, I'm using map-matching function quite successfully.

But as I was investigating some strange behaviors in my neighborhood, I wanted to quickly test the result of my map-matching on some problematic ways / nodes.
I was hoping to use a tool such as https://docs.mapbox.com/playground/directions/ to do this troubleshooting but with map-matching request.
Since such tool doesn't seem to exist I've mixed the request prepared by that tool with the one from https://docs.mapbox.com/help/demos/get-started-map-matching-api/index.html (that does map-matching but not pedestrian).
By doing so, I realized that the direction API and the mapmatching API didn't answer the same thing to a similar query :

https://api.mapbox.com/directions/v5/mapbox/walking/5.800798037396589%2C45.21580602782012%3B5.801456870627447%2C45.215414481183615%3B5.801700058007384%2C45.21492591634032?alternatives=true&geometries=geojson&steps=true&access_token=MY-TOKEN

https://api.mapbox.com/matching/v5/mapbox/walking/5.800797650898716,45.21581080651953;5.801424456929027,45.21542164580532;5.801674116958651,45.214942675116106?geometries=geojson&radiuses=25;25;25&steps=true&access_token=MY-TOKEN

Even if the format could be different, I didn't expect the filtering of the ways and node to be different : it seems that mapmatching is blocked at a node : https://www.openstreetmap.org/node/746410976 when direction is not.

I don't think that the parsing of the map should be any different while using both API to come up with a pedestrian path.
Am I wrong ? Is there a good reason it should be different ?
or is it, as I expect, mapmatching API being less accurate ?

where can I find the filtering rules applied in both API calls ?

Thanks for investigating,

使用列出的 SDK 版本和坐标，复现 Directions 和 Map Matching APIs 所示的步行请求，然后比较它们在 OpenStreetMap 节点 746410976 附近的路线。检查 API 文档或 repository 参考，了解过滤和步行路径规划规则；完成的标准是记录差异的原因，或确认一个可复现的 API bug。
