No, the triangle brace installed as designed, "spreads" the load over a larger area.
If you turned it upside down, the weight would exert "pulling" force on the hardware attaching it to the wall, greatly reducing the load capacity of the shelf.

The shelf support may or may not bear the weight of the shelf and the load depending on the type of fasteners used and the structure to which it is attached
The real issue becomes supporting the shelf and load. A shelf support, be it a bracket , triangle or even cantilever, is designed to bear the weight from underneath. For example a shelf and load can be placed on two or more supports without the shelf even being fastened to the supports. However, if the support is turned upside down the shelf is no longer resting on the supports, but is being suspended. The load that could be placed on the self is directly dependent on the fastener used to attach the self to its suspended support.
Rule of thumb, whenever possible support a shelf from underneath.

It will be as strong in either direction, and it all depends on the top screw in either configuration.
In the normal configuration, the top screw which is near the shelf is in pulling mode. The bottom screw does almost nothing because that part of the bracket is pressing against the wall.
In the upside down configuration, the top screw is in pulling mode as well. The shelf and the bottom part of the bracket push against the wall.
Imagine attaching the shelf to the bracket first, in the upside down mode, and hanging the bracket(s) with the top screw. It would stay there without the bottom screw.
In addition to pulling, which is caused by the twisting action of the shelf and load, there are shear forces straight up and down. These are rarely the limitation.

to be sure, put triangle brace both on top and bottom of the shelf.

With the brace on good, there is greater stress on the screws conserving the coolest of the brace to the wall, however the brace itself is greater suited because of the fact, in stress, it won't be able to buckle. you in addition to could have stress on the screws conserving the shelf below the brace; while the brace grow to be on the backside no screws have been mandatory to connect it to the brace.

If you mount the screws in properly and they are large enough to not pull out from the wall, the results do not differ.
However, the screws are being pulled and this can lead to failure over the long haul.
